This is the only "School" series that I watched. Never watched School 2013/2015, but I think this is a great drama to watch.

I must say, the plot is great. The investigation to find X, the relationship of the parents and the main roles, the corruption of the administration, the rich students and parents who dodges the bullet every time, the romances of the roles, the friendship, bullying, etc., there are a lot of things going on in the drama which makes me have mixed emotions like anger, happiness, anxiety and romantic excitement. The last 2 episodes are a bit rushed for me because I wanted it to be longer to keep the flow of the story smooth that's why the points are deducted. Other than that, I think the story is amazing and it leaves life lessons.

The cast, they executed their roles amazingly and it makes me amazed too. Kim Se Jung (Eun Ho) & Kim Jung Hyun (Tae Woo) fit through their roles and make up a cute and lovable couple which is great to watch, and their acting is so good for rookies and I didn't know that their just new to the acting business. Jang Dong Yoon (Dae Hwi) and Seol In Ah (Nam Joo) also make up a great couple. Can't believe they're new to acting too, they executed their roles so well. Other than that, other casts (villains, staff, other students) did executed their roles very well so I gave it a 10.

The music, I don't mind the music at all. I just deducted .5 because there are some music that didn't hit my emotions.

Overall, a great drama to watch and if you can handle your emotions well, you can watch this drama. :)
