One factor that I gave it a perfect score is that the genre of this K-drama series Is my favorite.
This show portrays close to realism of Judiprudence set-up. More to that, Juvinile Justice is a hotpot law even to my country, the Philippines as of this point. Moreover, this talks a series of Criminal issues of a teenager, where it reflects the face of society and next generation-to-be adults that if they are not being reprimanded by their actions they would have their lives destroyed.
