Is Yuki really that messed up because of Touru? I mean she can't even move on from what happened unless Utsumi does her where she did it for hte first time with Touru. Maybe it's more of a mentality thing, to believe something good can happen in a bad place, especially with Utsumi who was always nice to her.
Too bad Utsumi was too nice to refuse to do her. Yuki felt that guilty for not being able to have sex with Utsumi that she broke up with him. Now, he's with that other girl whose name I forgot. I don't mind her that much since I like her and she's cool, unlike Oonuma. I still prefer Utsumi with Yuki since they're the perfect complement to each other.
