Marliver but like in the way where they're both arospec & Marcus is mostly touch-averse except w selective people and Oliver has OCD & can't touch anyone for multiple reasons anyway. But they manage to be each other's safe space because hey, they Get It. And Marcus doesn't do romance or even friendship but they like attention (NPD) and they get super possessive/attached (BPD) so Oliver is Theirs And No One Else's, Thanks. And Oliver is super codependent and clingy as we all know so this arrangement works out fine. Their relationship might even maybe one day progress to (gasp) holding hands (gasp) in public. Or maybe just maybe one (1) hug when one of them's on their deathbed or something.
