most people are going to rate this low because of the fact that the mc and his rapist end up together, but I think this wasn't meant to be a happy story to begin with. Harada's ending wasn't meant to be a good one, it was meant to be bad. In the last line of the story the mc tells himself "we're not wrong" as if he is trying to convince himself that what they're doing is healthy. The message behind this really hits hard if you pay attention to it. A really sad story about grooming and the cycle of abuse with a sad ending.
