At first, when Milo went to fontaine to study Elynas, they didn't get along well, due to Milo thinking he'd be similar to Alhaitham personality-wise, but quickly grew to be good friends, or more... Nobody knows the details of their friendship, but one can tell they have grown close during Milo's stays in Fontaine.

Kaveh is a good friend of Milo's and the two of them tend to go drinking together at least once a week, talking about different things. The topics do usually circle around to the architecture of ancient ruins every time.

One time while exploring underwater ruins, Milo accidentally "broke into" the Fortress of Meropide. After explaining the mistake to the Duke, they had a good laugh, but Milo was still forced to stay for a while until everything was cleared on paper. During his time at the fortress, he became friends with Wriothesley and still visits him for tea occasionally when he is already in Fontaine for one reason or another.

She reminds Milo of a friend he used to know back in Snezhnaya. At first he was unsure about becoming friends with Navia, but as time went on they seemed to naturally get along well and now will always go out for tea at least once whenever Milo visits Fontaine.

They barely ever talked, but Milo respects her fighting skills and really wants to duel her, but never got the chance to ask.

Milo dislikes the fact that she keeps trying to pry into his past and is terrified that she might find out who he used to be and reveal it to the world. Whenever he's in Fontaine he desperately tries to avoid her whenever he can.

During his time and his countless visits in the Fortress of Meropide, Milo has only ever talked to her a handful of times. He isn't sure if she is avoiding him for some reason, or if timing has always been to blame for her being busy whenever he's around.

They have met a few times when Milo was traveling through Liyue. While they do tend to get along, Milo is wary of him, due to his search for immortality and the eerie similarities between Baizhu and Regrator, especially appearance wise.

The two of them are good friends. Milo met Albedo by chance when he was researching the lost civilization of Sal Vindagnyr on Dragonspine. Now, they write letters every once in a while and meet up each time Milo goes to Dragonspine for research.

Despite both of them sharing many habits, they never seem to be able to get along. They tend to try to avoid each other, but due to the research papers Milo has to hand in and Alhaitham's work as a Scribe, they are forced to meet every once in a while.

Milo has met Amber a few times while staying in Mondstadt for research. It is clear that Milo gets a bit irritated when she's around, due to her hyperactive nature. Despite this, they work well together if she accompanies him into one of the ruins.

They have met only two times. Once, when Milo was on a mission with the Fatui when he was very young. He had gotten lost in Inazuma City and Ayaka had helped him find his way back to the entrance if the City. The second time when he was already with the Akademiya and on his way to study Enkanomiya. She recognized him and they went to get tea together, catching up abouteverything that happened since then.

Ayaka had told Ayato about meeting a young Fatuus and years later, during Milo's second visit to Inazuma, they finally met. Despite Ayato's reservations at first, the two of them did get along fairly well after Milo told him he was no longer with the Fatui.

The two of them don't get along at all. Milo dislikes Barbara's incessant worship of the Archons, while Barbara dislikes Milo's disregard of the Gods position in the world and his belief of them being equal to humans, not above.

Milo and Beidou get along incredibly well. When traveling, Milo usually goes with the Crux whenever possible. The two of them get absolutely wasted when together and Milo laughs at Beidou the next day if she has a hangover. Nobody understands how Milo never gets hungover.

Bennett reminds Milo of a friend he used to have at the orphanage, before he died during a mission in the Fatui. This caused Milo to be protective of Bennett, teaching him some techniques to be safer. Bennett was surprised at his kindness at first, but quickly warmed up to his new friend.

When Milo first met her, he instantly noticed her eyes and, after talking for a while, figured out that she is a descendant of the Scarlet King. Ever since then he's been pestering her with questions to a point where she had to start actively avoiding him to get some work done.

Milo and Ajax were good friends when he was still a Harbinger. Both had a love for battle and sparred nearly every day. Ever since Milo left the Fatui, their relationship has become complicated. Ajax wants Milo to return to the Fatui, while Milo has long since seen the true evil of the Fatui and has started to dislike Childe for the things he has done.

Despite all the times Milo has been to Liyue, he has never been able to talk to Chongyun. This is due to the strange aura the young man senses around Milo, feeling it is safer to avoid him.

Collei is the only person in Sumeru that knows about Milo's past as a Fatui harbinger, having seen him several times when she was still dottore's test subject. She avoids Milo like the pest and Milo is scared to death that she would reveal his past to someone. She has no plans to do so, though, believing that people deserve a second chance.

Cyno has been wary of Milo ever since he first appeared in Sumeru out of nowhere. Despite his wariness, he remains polite and seems to slowly be warming up to Milo. They have even begun occasionally playing Genius Invocation TCG together.

The two of them have met once, when Milo paid her to protect him during an especially dangerous research trip. They worked well together and their fighting styles seemed to complement each other well.

They met when Milo had just left the Fatui, and traveled together for a few weeks. In those weeks Milo became increasingly interested in Khaenri'ah, asking Dainsleif many questions. They eventually parted ways, but Milo hopes they would meet again soon, now that he has researched Khaenri'ah for so long he wants to present Dain with his findings.

Diluc has been keeping a close eye on Milo every time he is in Mondstadt, clearly wary of him because of the Snezhnayan vision and the sense of familiarity he feels when looking at him. Milo, in turn, seems to avoid Diluc's presence, remembering the killing spree Diluc went on in Snezhnaya years ago.

Diona dislikes Milo because of his drinking habits, while Milo loves the drinks Diona prepares. Since Milo avoids Diluc, the Cat's Tail is his go-to bar in Mondstadt, spending nearly every evening there if the doesn't camp out on Dragonspine.

Milo often comes to Dori to buy relics she has found, or sell relics he has no use for. The two of them have become good business partners. Though, there is still a sense of distrust between the two, due to Milo's high rank within the Akademiya and Dori's shady business.

The two of them don't get along one bit. Milo dislikes Eula's snobbiness and, in turn, Eula dislikes Milo's belief that everyone, even the Gods, should be treated equally. After a rather nasty argument, the two of them now avoid each other every time Milo is in Mondstadt.

To the surprise of many, these two actually get along exceptionally well and often conduct research together, if they have their eyes on the same ruins. Even while they aren't actiely researching, the two often go to grab some tea together during breaks between lectures, talking about new findings.

Milo finds her antics quite fun and often goes along with it, causing Fischl to give him the title of her royal knight. Every time Milo is visiting Mondstadt, he brings her a little relic he found in one ruin or another, much to her delight.

Ganyu and Milo get along quite well. The first time they met they bonded over the fact that neither of them are entirely human and feel as though they never fully belong. Now, whenever Milo passes through Liyue, they try to make the time to grab dinner together.

They met at the Sanganomiya Shrine while Milo was on his way to Enkanomiya. They do get along quite well, talking about fur care and fighting techniques whenever Milo visits to research Enkanomiya.

One time while Milo was in Inazuma, Heizou pulled him to the side to tell him he knew about his past. Milo is very surprised by Heizou's ability to figure things out quickly and easily. Despite the surprising start, they don't dislike each other. Milo even seeks out Heizou if he needs help locating a ruin.

She has offered Milo discounts on coffins so many times due to his risky job to the point where he has begun avoiding her as best as he could. When she isn't trying to get him to buy a coffin, just in case, the two get along fairly well, talking about the darker things in the world.

Milo hates Itto's attitude and ever since they first met, has made it his mission to never run across the Oni again in his life.

Milo has helped clear out many ruins in Mondstadt while researching them, which caused Jean to have a lot less work to do. While the two of them rarely have the chance to meet, they have mutual respect for each other and have helped one another out many times.

Kaeya and Milo get along well. Milo has told Kaeya many things about Khaenri'ah and, in turn, Kaeya has accompanied him into many ruins as additinal protection. They also tend to go drinking when they find the time.

The two of them are practically inseperable when Milo travels with the Crux, often spending time together just talking or watching the skies. To many it might seem like there is something more between them, but they will be quick to assure everyone that they are simply very good friends.

Keqing seems to sense that something is up with Milo. She has been wary of him ever since he first visited Liyue, seeing the way he shiffles on his feet when walking past the Northland Bank and his nervous looks should a Fatui agent notice him make her think there is something he is hiding.

Milo finds Klee's destructive habits hilarious and sometimes fuels her nature by supplying her with materials to buy bombs with. Once he found out she was Alice's daughter, he became more interested in finding out if Klee knew anything about Khaenri'ah, but she is way too young to understand his complex questions.

Kokomi has helped guide Milo to Enkanomiya and allows him to stay at the shrine while he researches the lost civilization. The two spend little time together, but they tend to get along well enough.

Since Milo avoids Itto like the plague, the two of them barely ever meet, but Kuki Shinobu has helped him avoid Itto on multiple occasions. She did this mostly to make sure Itto didn't say anything stupid to really piss Milo off.

Milo and Layla barely have anything to do with each other, but when they do they usually get along well. Occasionally they meet during breaks between lectures to talk about research, but Layla is often too busy to stay for long.

Milo finds Lisa's powers and attitude very intruiging and tends to visit the library at least once whenever he's in Mondstadt. Her flirty nature entertains him and he often flirts back, though nothing serious has ever come of this habit.

Milo often goes to Mika for maps to locate ruins, but other than that they have little to do with each other.

They met once and Mona foresaw Milo's demise as an unstoppable event some time soon, causing Milo to instantly be put off by her. They haven't met since and Milo is left to wonder if she had told him the truth, but until now nothing had happened to him.

Despite Milo's dislike of the Archons, he does actually tolerate Nahida, since she doesn't see herself as superior to humans. She has also told Milo a lot about ancient civilizations and their fall. Nahida is also the reason Milo was able to become a teacher at the Akademiya.

In his free time Milo often visits the theater to watch her perform. They haven't met personally, but Milo holds a lot of respect for Nilou and her art.

Milo had been invited to the Jade Chamber once when she had somehow figured out he used to be a Fatui Harbinger. They talked for a long time, but eventually became friends, to the surprise of many. Milo even helped Ningguang design some pieces for her chess set.

Milo doesn't understand why, but Noelle seems to avoid him. He is sure he hasn't done anything to make her hate him, but he also doesn't really care enough to seek her out and ask why she avoids him.

Even though Qiqi keeps forgetting him, Milo quite likes her. Whenever he can, he tries to help her with things while also trying to keep some distance to Baizhu.

He disliked her at first, but one time he came across her seemingly lost about what to do in the middle of the city. He decided to just see if he can talk to her and found that she is actually a decent person to be around.

He dislikes the Shogun. The way she treats the humans of Inazuma makes him sick and he is glad Ei is working on changing some things about her.

Razor is wary of Milo and avoids him because he has the same scent as Fatui soldiers, since he is also from Snezhnaya. Milo has seen him in the woods sometimes and tried to talk to him, but Razor has fled each time.

Rosaria was wary of Milo at first, but quickly gre to like him because of their similar views regarding the Archons. Her, Kaeya and Milo often go drinking together.

Due to Milo's view of the Archons the two of them strongly dislike each other. Milo has made the decision to stay out of Sara's way to avoid unnecessary conflict.

Milo has stumbled upon Sayu once when he was looking for a ruin. When he woke her she was a bit annoyed at first, but then offered to lead him to the ruin he was loooking for. They haven't met since, but Milo is grateful for her help that day.

Shenhe watches Milo each time he comes to Liyue, sensing some strange aura around him, but she has never gotten close enough to talk to him. Milo knows she is watching, but doesn't mind too much.

Milo adores Sucrose and has basically adopted her as a younger sister, helping her with research whenever he can. Surprisingly, Sucrose seems more confident when he's around and he has gotten her to be less embarrassed about her ears.

To everyone's surprise Milo and Thoma seem to avoid each other for some reason. There seems to be something the two are hiding about a possible common past, but nobody has been able to pry any information regarding this out of either of them.

Milo has come to Tighnari for treatment many times when he got hurt in a ruin and they get along well enough. However, Collei's fear of Milo makes him wary and he tries to avoid unnecessary contact.

Before Milo figured out he is the Anemo Archon, the two of them went drinking a lot. Afterwards Milo began pestering with questions about Khaenri'ah and the role he played to a point where he told Milo to leave him alone.

The two of them have a mutual agreement about keeping each other's secrets. Milo remembers who he is, despite having been erased from Irminsul and Wanderer remembers that Milo used to be a Fatui Harbinger.

Milo absolutely loves the food she makes and, when on the road often hopes he would run across her. In general, the two get along very well too, often joking around or sharing recipes.

Surprisingly, Xiao doesn't seem to mind Milo's company at all, and whenever Milo stays at Wangshu Inn, they spend the evenings talking for a while. Xiao allows this, since Karmic Debt doesn't effect Milo's species and he seems glad to have someone to talk to every once in a while.

Due to Chongyun, Xingqiu often stays away from Milo, but the few times they have talked they seemed to get along fairly well. They even exchanged some book recommendations.

While they haven't met personally, Milo quite likes her music and sometimes makes his way to Liyue to catch one of her shows.

She makes Milo uncomfortable. The one time he visited the Grand Shrine she tried to get him to wear one of the shrine maiden kimonos and pose for her. He avoided the shrine ever since.

Milo is unsure if he likes her or not. They mostly get along, but sometimes they butt heads and an argument ensues. They try to avoid more heated or political topics when they do meet now.

Milo is very sure that she knows about his past somehow, but she hasn't said anything yet. The few times they talked it was pleasant, though the politeness was very clearly an act, both wary of the other.

When Milo first went to Inazuma as a young Fatui soldier, he met Yoimiya and she quickly became friends with him, giving him some fireworks. They stayed in contact through the years and now he takes the time to visit her every once in a while and lights some fireworks with her.

Milo absolutely adores her performances and tries to catch at least one of them whenever he's in Liyue Harbor. He even managed to get her to sign a small Cor Lapis chunk he found.

Milo would be lying if he said he didn't find Zhongli attractive, but due to his closeness to Childe, he tends to keep his distance from the former Geo Archon. The few times they did talk, they talked for hours about all kinds of historical events.

Pierro terrifies Milo and ever since he left the Fatui he is scared that Pierro might one day show up to drag him back to be a Harbinger again.

It is due to Capitano's kindness that Milo was able to leave the Fatui. When he fled, it was Capitano that was sent to bring him back. During their fight Milo gained his Vision and Capitano allowed him to flee. He owes him a lot and hopes to thank him one day.

She raised him and he is still grateful for that, but he knows what she is capable of and what kind of person she truly is, so he wouldn't hesitate if he ever faced her in a fight.

Milo hasn't had much to do with her in the past, but she seemed to be quite rude to him whenever they did talk.

The only Harbinger that showed him actual kindness. He misses Pantalone sometimes, but it isn't enough to make him even consider ever going back to the life he had.

Dottore tried to experiment on Milo quite a few times, saying that he was intrigued by Milo's species. Milo is creeped out by him and even as a Harbinger has avoided him as much as he could.

They hated each other when she was alive. Nobody quite knows why, even now. Milo was more than happy when he had heard of her death.

Milo despises him. He says Pulcinella is a liar and cares for nothing but his own gain. A heartless and selfish monster.

Milo is absolutely terrified of her to the point where he won't even say her name anymore in case she is listening in somehow.

Milo, also having grown up in the House of the Hearth, has known Lyney since their childhoods. They used to be close, but after Milo left the Fatui, they haven't spoken and Milo tries to avoid Lyney whenever possible due to Lyney's loyalty to Arlecchino.

Both of them grew up in the House of the Hearth, but never really got along well due to their difference in personality.

Milo and Freminet used to be best friends when growing up at the House of the Hearth, but now that Milo is no longer a part of the Fatui, he avoids Freminet because of the guilt he feels for leaving him behind.

Viktor and Milo grew up together at the orphanage and are still good friends, even after Milo abandoned his spot as a Fatui Harbinger. Milo visits him whenever he's in Mondstadt, not caring what others might think, if they saw him with a Fatuus. Their friendship is more important to him. He has tried to get Viktor to leave several times, but stopped after it nearly turned into an argument.
