Must watch kdrama

Definitely a great Kdrama to watched.
This is just made for young teenager to watch does not contain much romantic scenes but it was nice.
I wish there were more episodes.
I was just hooked on it.
Main lead couple were looking so cute together. It was a short one but still I loved all the episodes.
The story line could have shown the back story of the main lead more.
It sure raised awareness about school violence and bullying.
I was really in love with the ost.
I also loved the cameo of yeonjun.
