What to say... this drama was just a masterpiece !!!
It was my very first lakorn and I'm not disappointed at all, I just took a little bit of time to settle myself into the language but honestly it is perfect.

Regarding the scenario, don't expect a romance, each episode tells a different story (except the ep 6-7 & 12-13 which are connected episodes) with different characters except Nanno and the similarity is that it takes place in high schools. I absolutely loved the fact that it was several stories in one drama and the concept of punishing bad people. It shows their real themselves and give them a sanction depending on how serious their actions were. I appreciated all the episodes although there are some I loved a lot and some other a bit less.

My top 5 :
1st : ep. 2
2nd : ep. 8
3rd : ep. 11
4th : ep. 5
5th : ep. 4 and ep. 12-13

About the actors : choosing Kitty as Nanno was a very good choice, she plays magnificently this character. I heard mixed opinions about her artificial laugh but it didn't bother me because I think they asked her to laugh like this on purpose because she is not really human and we can see her ''devil's daughter'' side. All the actors of each episodes were playing well too, I had a little firm favourite for Best Ekawat Niratvorapanya who plays TK in the ep. 8.

Trivia : each episode have been made by a different director and all the stories told are miscellaneous news item that really happened in Thailand's schools.

In conclusion this a super lakorn, I recommmend it at 100% ;)
