I think they forgot the sychological tag
*p since the ml is too real for a fictional story, he's mentally unwell and it shows through his perspective, his impulsive behavior which led to immoral acts such as rape, his impaired worldview that prevents his growth, and his objectify of his friend as a mere tool to exist for his amusement (if he doesn't have any function for me, then there is no value)
It's a great analysis, if that's really the author's goal then it's a shame that it's classified as simple yaoi because for this genre it's a bad story
But when ans why do you write a story like that? I just want to disembowel Mirai and throw his guts off a bridge. Shitty and useless story, no point in reading it
