The story line.

At first, I was annoyed with Han Tae Yi because he was too much, even though Yoon Se Heon just wanted to practice. But as the story went on, I slowly started to understand him. I began to feel sorry for him as I got closer to the end of the series. Still, it's a two thumbs up for me. It was really good, and I'm happy that it had a happy ending for both of them. Big thanks to Se Heon's brother. ?

I can say it's a must watch series. it's worth it. The story is not that too complicated to understand.
