it is a thing i do!! with shuji it really depends on the tl buuuut i've been into final tl the most recently so we'll go with that. he's very chill abt it! he'll play games and watch things with me. we play mario kart and pokemon together the most! he'll also bake things for me if i want them. chifuyu i think is the most caretaker-y out of the three of them, he's always making sure i'm doing okay, checking in, that sort of stuff. tora was surprised at first and like "wait there's a word for that? that's an actual thing?" and sometimes he will with me and we just chill together and it's very nice <3
