I'm going to editing stuff into this more, but here's something

Main Couples (with brief(or not so brief) descriptions of how they met/ what their relationships are like)

Wyatt and Mallamark

•  https://artfight.net/character/59320.6-wyatt-wp-alt and https://artfight.net/character/59345.6-mallamark-wp-alt
• Mallamark is extremely infatuated with Wyatt, and his feelings for Wyatt seem mostly one-sided at the beginning. Mallamark doesn't really mind since being with Wyatt is what's most important even if the feelings aren't reciprocated. 
• Wyatt doesn't dislike Mallamark although he lacks much interest in romantic relationships (Wyatt is aromantic pansexual). He's not against having a "deeper then friends" bond with someone (i.e. with Malla) but he's not very good at expressing himself, so development towards that will be very slow for these two.
• They do eventually get together.
• Things to note. Wyatt generally doesn't really like close contact, but generally puts up with Malla (who apparently needs lots of physical contact). The only time Wyatt will initiate a hug/ cuddles/ etc. is when he's cold.

Lochrael and Yulius

• These two were husband and wife in their previous life, but died in an accident and they both happened to reincarnate in a fantasy world.
• By chance they reunited, but on opposite sides of a demon vs. human war. Both retaining the memories of their former life together and it took zero effort for them to get back together.
• They are a somewhat obnoxiously lovey dovey couple, and expect lots of public displays of affection. 
• Due to Yulius blaming himself over the accident that caused them to die in their previous life (even though the situation was out of his control) He's very overprotective.

Avene and Kayla

• Kayla genuinely disliked Avene when they first meet because he was kind of an ass. Avene was completely indifferent towards Kayla.
• Due to struggles the two go through during the events of the story, they both grow as individuals (esp. Avene) and eventually become very good friend.
• At some point they realized that they hit a point where they were potentially more then friends and became lovers. They aren't likely to ever marry due to marriage having a different meaning in the culture Avene was raised in compared to how it is viewed on Earth.
• These two really enjoy joking around and teasing each other. 

Kyze and Talon

• Kyze grew up with a very dark past, formerly being an assassin, but due to events he finds himself free from the chains that bound him to that life and he got to start anew (or so he thought). He met Talon after he chose to become an adventurer.
• The two got along really well, despite Kyze being uncomfortable around strangers.

Ffaralder and Valsparra

https://artfight.net/character/461835.5-ffaralder-ff-alt and https://artfight.net/character/514039.4-valsparra-ff-alt

• These two originally met when Valsparra (in a delirious state after being cast far from his home in a storm) attacked a phoenix only to be stopped by her friend Ffaralder, a powerful phoenix mage. Due to the land's laws, Valsparra was to be an servant to the one he attacked for a year, but she was uncomfortable in his presence and declined. It was decided he would serve the one who captured him. (Ffaralder wasn't really interested in having a servant, but if he had denied, Valsparra's punishment would have ended up being more severe)
• As Ffaralder spent most of his time focused on his magic research, he never gave Valsparra any orders to do anything. Although in his boredom Valsparra ended up cleaning and doing various tasks around Ffaralder's home (The lifestyle Valsparra previously lived was no where near as calm as life in the forest, granted it was a bit boring Valsparra enjoyed it)
• After a few months, Ffaralder decided to seek a pardon for Valsparra's crime that would release him from servitude. Ffaralder was leaving on what was to be a short, but potentially very dangerous, journey and should something happen to him Valsparra's sentence would continue but with a new punishment.
• Even though Valsparra was free from his punishment, he chose to go with Ffaralder. On their way to the destination a strange monster attacked. Ffaralder was gravely injured and due to their inability to fight the monster. Ffaralder cast a forbidden spell. The monster was defeated, but the spell took Ffaralder's life not even leaving a trace of his body.
• After this Valsparra realized he cared
