oh the angst potential of this … 😟 (😈) i think if Katsuki had run into Tetsu first that night, it’s pretty likely they would’ve hooked up and it would’ve turned into a fwb situation. and someone WILL catch feelings first and ofc it’s gonna be Tetsu 😭 Katsuki would be super hot and cold 😞 he wouldn’t open up very easily bcs of Tetsu’s reputation as a fuckboy, so even if Katsuki did like him a little bit, the entire arrangement would just be about sex for him. Tetsu would be fighting a long uphill battle as soon as he realizes his own feelings 😭 they’d keep their arrangement secret for a very looong time. and it would be on-again-off-again as soon as Tetsu admits to wanting more 😭😔 but even after that, i could see them working out long term if Tetsu really put in the effort to show Katsuki how committed he is.

Ei would figure it out /right away/ and it’s instantly heartbreaking ❤️‍🩹 but he’d try to pretend it didn’t bother him 😭 eventually he’d just distance himself from Tetsu because it would hurt too much 😞 their friendship would be pretty strained for a while and Tetsu would just have no clue why because Ei would feel too guilty about admitting his feelings 💔 idk i think eventually he would be able to work past it, especially if Tetsu really loved and cherished Katsuki 😭 it would take Ei a very, very long time to get over it though.
