II was hating Mitani in the last few chapters. But now I'm just pitying her. She clearly doesn't like Yo in that way, even when she has accomplished what she was aiming for. I can't get over the empty expression she has while telling Yo she wants to do it with him again some time. Not only is she hurting both Yo and Kei who are supposed to be her friends. She's also hurting herself by forcing herself and going this far.... and for what? What is her end goal here? Does she not feel regret? Then if Yo goes back to Kei and ends up leaving her, she's the only one who will be hurt the most. It doesn't help that Yo is as indecisive as ever and is pretty much being led on by lust. At this point I don't even know who he likes anymore.
