I'm sorry but if a dude makes a whole MOVIE with you and for you, how could you NOT proclaim love? I understand if it's unrequited/not asked for, but god damn the obliviousness is irritating. I wish Ruka would stop acting like a prick and take the hint, I wish Mami didn't just fade away from the story, I wish Chizuru would actually admit she likes him or for Kazuya to grow a backbone and say he likes her, and Sumi can be Sumi she's fine and so is Mini aside from her Master schtick.
I don't even remember WHY Ruka needs to be kept on as a side-ho-- I mean "girlfriend". It's not like we've seen Kazuya's friends in the last dozen or more chapters. She's clingy, annoying, selfish, and although she's done nice things it's always with ulterior motives to "get closer to Kazuya". I understand why Chizuru isn't willing to admit she wants to be Kazuya's GF, but god dammit... After all he's done, she just needs to come out and say it.
