Honestly this is a very gripping twist and turn type of psychological 89 chapter manhwa that makes your head spin! It portrays terrible and very sad circumstances very well on what each characters has gone though/is going through. For example their type of events touches on the basis of paedophilia, murder,self harm, PTSD, domestic abuse, bullying, negligence and suicide. I would not suggest this manhwa to people who might be triggered by the above topics I said there. I personally thought it was very good but very sad, unpredictable and sinister so this story is definitely not for the fainted heart. It's also definitely not alovey dovey story between a student and school nurse as you might expect!
