Ok so Nanase kisses Momo when she can, Momo doesn't even ask why is she doing that or..I know this is fiction and you can't have manga (usually) if people talk about their real feelings, because then you have no story to present, but come on!! if a "friend" did that to me , I'd be like... "so, you want some of this or?" ( a female friend of course, since being a raging lesbian is a trait of mine well known far and wide in the land)
