So, the plot was really good. I mean, the plot about bullying, lies, manipulation and so on was really captivating... But in this drama as well as many others, the screenwriters add too much romance. They also focused on the girl's life too much in the middle of the drama. I think the drama could be really better without all of the useless scenes of romance ; but if you're really found of romance, I guess this drama is a really good one for you. But they also rushed the end and it was not as good as expected.

But I really liked this drama for the development of the main character, the development of his relationships and of his self-confidence and self-esteem. He was so cute and the actor was breathtaking. The Homeroom teacher was too nice and it should be awesome having a teacher like him. I really liked his role.
I put a 9 for acting/cast cuz I find the main girl was too much, I didn't really was found of her acting. But I find that the acting was really good overall and the actors were really into their character, it was really captivating to watch - just didn't like this girl...

The OST were pretty good and accurate with each moments.

I put the rewatch value at 5 cuz I guess if I have to rewatch it for some reasons, I will like the same points (but also dislikes the too-much romance huhu).
