I'm a big fan of highschool dramas and music dramas and this one was the best combination of both. This drama made me feel so old and reminded me of my old days in high school. The stupid crazy first crush stories, the funny embarrasent moment, the bad parts of teenagehood, all of them were perfect in this story! I laughed, cried and enjoyed every scene. In music drama there is always that one or two songs you get bored in. But all were perfect in Monstar!! Some made me super excited. All the characters had very interesting stories and were interesting for me. I really laughed a lot thanks to Sul chan, Se yi and Kim NANA. I really laughed a lot during this drama. It has been a while that I haven't seen such a good drama :D Thank you for existing >/////<
