Didn't I read this already? Can't remember the story, lol. - Well, I'm not sure if I did but it's a good one! 5* for basically everything. Art, smutty art, story, character growth, drama... It's all great! The only thing missing is a reunion/reconciliation with Hayashida's ex, and I'm not sure if that's supposed to be his high school friend from the first couple or not.
