Kami loves being in the middle whenever they do anything (especially cuddling) and is the smallest so fits in between the other two perfectly
People usually assume that Kirishima is the glue that holds them together but Bakugou and Kami get on really well once they find common ground and Bakugou will yell at people who think otherwise
Bakugou and Kirishima always reassure Kami about his intelligence and potential and that's just the tip of the iceberg.
Bakugou is actually crazy protective and will fight anyone who even utters a bad word about either of them.
Kaminari and Kirishima also do this but Bakugou never notices, they're subtle to protect his pride but will fuck you up.
One of their favourite affectionate things to do is just play with each other's hair because honestly they're all so extra in that department. Also their spiky hair is all inexplicably super soft and silky smooth too.
Their dates usually just involve snuggling up on the couch and playing video games or watching a movie which somehow always end with Denki falling asleep on top of the other two.
They carry him to his own bed and tuck him in.
