Really good in a strange way. I think that the only thing that made me a little uncomfortable here was the fixation with the sex scenes that are related with rape. It's a long disgusting scene and the manga seems to try to sell it as something hot. That was a little disturbing for me due to the kind of story I was reading, but narration in general is pretty good and characters work so well with it.
Little details like the mother not being a complete monster his whole life, Kousuke who in general is a good person but still slept with a minor (probably even knowing he was lying about his age), or this that even when there is a happy ending, those guys that rape him until unconsciousness may never pay for what they did... so many little details for such a sour but good story. Rough but sooooooo good.
