such a quick read, at first i tought it would be another revenge history where the mc is the badass and fucks everyone that had hurt him, and well it is, but is a good one, it's a history about bullying, mostly about the bullying that a girl suffer from her colegues and how her teacher who was also bullied in the past (and one of his bullies were her father) helps her to get revenge on them, and while sometimes it kinda is clear that is all fiction i can see that the author tried their best to make the storyline be loyal toour world,i liked how in the end of the manga the teacher kept helping other people to get over the bullying, is a pretty message(and also as a bully victim i related so much to the mc) really fun!!!!
