Yeah, I guess the title was a little weird, but yeah, I think this would be a nice way to shake things up, without breaking the established lore, especially of Yuu being gay, which is why we won't get a Class Rep route or anything
You're probably not the only person who thought that, but I believe the implication is that Yuu only being attracted to men is why all his past relationships with women have failed, and that he only got into those relationships because they asked him out and he really struggles with saying no.
