I've never been a big fan of school dramas or series. But frankly, this drama made me change my mind.
Of course there is the school side that I don't like but that i had to expect it.
The story is interesting, it's full of suspense and the actors play really well. The OSTs are really good and the filming well done. I immediately got attached to the character and their story.
If you wants to understand the pressure in Korean schools and the life of young people in Korea. I recommend it because I saw it in full and if you knew me you would be surprised.
