Very decent title. Controversial relationships, various characters, and most importantly, it doesn't seem that the author tried to make this title as edgy as possible for the sake of being edgy. It feels well-written, and it serves as a constructive element of manga. And sex scenes are very intense and hot. So bad it's ended a little bit awkwardly without a proper conclusion for all characters, not only for the main couple.We need more the seductive teacher trop in anime.
