ooooo, i dont know, maybe? the way i view them, i think Suguru needs much more affection and reassurances than she's comfortable giving, and he needs someone that has a firmer grasp on things that can tell him "Stop. This is what we're gonna do. Relax" (basically what we see gojo doing for him when he starts panicking during the SPV mission). Shoko can't really provide that.

also i think Suguru's too in his head and neurotic for her, and she just doesn't take it seriously at all, so i think she'd be frustrated with him after a while. also she's sooo emotionally closed off, even more so than gojo, i think she'd get to certain point where she'd just shut down on him. and then suguru would shut down too.

So i tend to think it would end up being a somewhat frustrating relationship for both of them, thought without any sort of open conflict or passion. Also as a personal headcanon, i think they're both pretty low sex drive individuals so they just would have sex very infrequently, lol. which isn't a good or bad thing, it's just a thing, you know? headcanon. i love writing Sugu/shoko and sashisu, though. i need to write more.
