How ironic would it be if Chifuyu finally fell out of love with Ichika and in love with another guy, only the guy is about Ichika's age
but he tells her that he sees her as an older sister because she's been treating him like a younger brother all this time?
I know I've asked this before and that Yamada would be a good example. But would Chifuyu react violently to everyone who finds out she's a brocon?
