Great show must see only 12 episodes but each has got something special going on. The episodes end in suspense and u wanna find out if that the episode kwan son ah will get caught.the evil person is so evil together with the bougie parwnts but after a few more episodes u get to understand her. The last few episodes help to clarify the conclusion of each character. I loved the homeroom teacher hes always that supporting actor who never gets the girl and is so kind hearted u feel sorry for him. This is like the school 2013 shows with bullying and kids lives but through cheerleadin P.s those are some mean ass parents
