I am happy that he is not abused anymore. BUT I feel like he had conflicted feelings after what's happening and his rapist did to him. I found this story to be very sad and I would very much preferred an ending where the protagonist didn't end up with his possessive rapist, but instead with his brother and try to restart their lives together. Nor do I believe that Ryou and his brother will be in be able to be in any sort of relationship that are intimate much less sexual.
