Owain
Manny and Owain work well in most universes after they get over some initial bumps. The more carefree attitude and willingness to just accept his fault without trying to fix it that Manny carries into any relationship usually rubs Owain the wrong way, when he works so hard to take responsibility for his past mistakes. But with a greater understanding that they’ve both come from different rough lives, usually the two can find a comfortable compromise between themselves and enjoy relaxing and growing old together.

Kazuya
There's something addicting about flirting with Kazuya, between how sure he is of himself and the complete fluster he ends up in moments later. Manny finds himself feeling like a joyful kid around Kazu, that he could take on anything. But the moment he's not directly around him, Manny ends up wondering if all of Kazu's scars and history had something to do with the fact that he walked into his life.

August
Drawn to how passionate the other was about his study, on top of the matching ebb and flow of flirtatious personality, Manny always ends up falling harder for August than he ever expects. They can easily become intoxicated with each others amourity, sometimes to dangerous extents, which results in a hurt far worse than most of Manny’s regular breakups.

Atticus
Manny and Atticus have a complex relationship, bent hard around loneliness, the desperate need for intimacy, and the exchange of knowledge for a price. It was never healthy, but at least it was a constant they could lie to themselves about. It never turns out well, but they have a hard time stopping…

Ada
Ada has everything Manny gets subconsciously drawn to in a romantic interest. He can sometimes get tripped up due to oddities about her that he doesn’t quite understand, but that doesn’t keep him from falling head over heels eventually. Their infectious curiosities help energize each other and keep the magnetism going, even with Ada doesn’t add any natural romance to the relationship herself.

Yukira
Manny and Yuki both have a more straightforward approach to things, as well as a similar lack of hesitation, so while there’s usually some mistrust and miscommunications to clear up from introductions, the two can easily fall into a partnership without too much issue. They find comfort in each other’s strength and independence, though their combined guilt might get the best of them some day.

Miteby Jones
Usually when Manny’s relationship with Jones is ever stronger than acquaintance so far, it’s in an almost loyal dog sort of way. Whether because he believes in Jones’s cause or simply is optimistic in the scientist, Manny wants to support him towards a better life. In some cases, that idea of a better life differs from what Jones is thinking of, but the two will have to cross that bridge when they get to it.

Dust
Dust and Manny are super easy to ship in any military situation they could meet in. Dust and Manny lean on each other a lot in times of need for comfort, and thanks to their free-flowing nature, even when having to break apart the relationship the two always kept a fondness for each other in their hearts. Dust’s similar calm aura meshes well with Manny’s, and is very good at helping Manny get through his own self depreciation and guilt.

Val
Val and Manny have a lot of potential for a good bond, but both are quick to immediately take the instant gratification option instead. They find each other in times of needing touch and exhillieration, and marinate in the fact that neither of them are comfortable digging deeper than that. It’s interesting when a bond between them is forced how they still try to ride as close to that ideal as possible.

Regis
Like Ada and Arin, Regis carries a lot of traits that quickly catch Manny’s eye. But his passion and dominant personality can easily overtake Manny, pulling him into a trap he might start to regret later due to conflicting morals, even though those morals are probably more conflicted within himself instead of between him and Regis.
