Actually, more will happen. some Shounen ai mangas have sex and nudity in them. It's clear who the main pairing is.. Carvel x Mano. So please dont post false information.

I'm totally willing to admit that there is a chance I will be wrong, but the manga *does* say that it's a shoujo story. http://www.mangago.zone/read-manga/vampire_library/bt/c003/pg-34/

Yea, its projected to girls. We have already seen some scenes that clearly convey romantic feelings. This reminds me of “Uragiri wa boku no namae wo shitteiru“ because in the past, Yuki was a girl but was reborn a man. Luka (his lover) says he loves him for who he is, not because of the woman version of him. Carvel in this story obviously had an “eve“, which is obviously Mano. Since its Shounen Ai, they dont always rush into things. I only responded because you said there were “no pairings“ when in reality, there are two (Carvel x Mana) & since the sexual harasser lady (forgot her name) and the other library helper (forgot his too) kissed, Im guessing they're a pair too.
I just started reading. Is this one of those "in the closet" shounen-ai?
