Imagine that on Yuu's second year, a lot of students get selected to ramshackle, and Ace transfers to become ramshackle's vice housewarden and help Yuu
because Yuu would have no idea about how to deal with ramshackle becoming an actual dorm, populated and all, it's basically like having to let a bunch of strangers live in the only home they have in this new world
also they would only have Grim there to help them defend themselfs and control the students, the possibility that the new students would turn on them would be terrifying
Ace gets worried, and decides to spend some days there, to help Yuu and Grim to feel better and help them while they figure out what to do
Yuu ask every housewarden and vice for some guidance on how to become a proper housewarden and take care of a dorm, and they are able to come up with basic rules for living, it helps a lot that the ramshackle students are much more chill than the average NRC student
Ace just stay there to help and sleeps on the room that was basically his since last year, while also doing his best to fulfill his duties in heartslabyul, but he has limited time and is tired, so the days he sleeps on heartslabyul becomes more and more rare
he keeps postponing the time where he will return "i can't just leave Yuu alone now" "everthing is crazy right now, maybe next week" "i need a few more days to resolve this okay?"
but after some consideration, and Deuce insisting, he has to admit that the way ramshackle works suits him much better than heartslabyul, without the nonsensical rules and all the reprehension, now that he experience a more normal routine, the control on heartslabyul feels sufocating
and also, he and the new students got attached to each other (but he will never admit it), and while he is still that easygoing troublemaker, the responsabilties made him grow a little
it's weird, it might be because he is a younger sibiling but he always prefered to let others take care of him, to have someone else deal with the bothersome problems
but for some reason, he goes to defend and help his dorm mates with no hesitation "protective", is what Yuu called him, teasing him
so after some thought, Ace decides to actually transfer to ramshackle "isn't it funny? i said i would become part of ramshackle on or second day here, but only now i actually do it"
oh, now that he doesn't have to wear the heartslabyul uniform, he would feel a little sad, the heart looked really good on him, he still wears heart themed, red acessories and eyeliner, tho now that he can, he alternates between red and darker makeup, like black or brow (tho it might be just my wishfull thinking since i think those colors look beautifull on him)
by the way, i imagine ramshackle 100% ships aceyuu, and Grim as their son (either they are romantic or platonic doesn't matter, shippers will ship)
Ace "i only permanently transfered dorms to help Yuu"
Ramshackle student B "...suuure"
