mc ran for 10 minutes bleeding to death, was shot, and still survived, also, he tortured the fmc for months, so he probably knew how to check if she was dead, but, at the moment he needed to most, he simply ran away without checking if she had died. And I don't even remember if he cried during the entire manga, either he's simply not human, or he can't cry. It's too much for a person not to have a breakdown at least once, too much for a teenager's brain. So in summary, a logical ending would have been with both MCs dead, which wasn't the case, resulting in a "happy" ending, 6.1/10 in my opnion
