Your standards for "rape" confuse me, particularly in this genre. Shou was once raped by Kunie, but not here, rather is was in the prequel / side story to this manga. In this story, when Kunie returned, he certainly startled Shou but was recognized and accepted right away. No different than your lover coming up behind you, covering you eyes in a "guess who" fashion and kissing your neck. Would you call that rape? Granted, he also grabbed Shou's penis, but between male partners who have "played rough" in the past, that is not uncommon. At the point Kunie grabs Shou's penis, Kunie is recognized and accepted, so no rape...surprise sex, sure, but not rape.
Surprise sex... Jeje. That's good. I agree with you. We can't actually call it rape because every time they have sex, Shou goes to Kunie's house of his own volition knowing what will happen.
I'm with you on this one. I can't help but think that he was being raped and continuely harassed to no point end. And then suddenly they easily get together?? I'm not convinced.
I don't really understand love that comes with humiliation and rape and sex is the only thing to bind them together. Kunie just plays with Shou continuously. He leaves for 3 years without a word and when he comes back he rapes him again. That is a weird way of showing your love. And what is with the weak characters always abused that love so strongly the abusers? beats me this kind of love
