If at first there might not be anything special about this drama, as each episode goes on, everything gets more serious. The beginning is cheerful, funny and light and the later episodes turn into mystery crime ones. In a way, I liked that the feel of it changed.

The story might not be so special but as you watch it, it keeps getting better and better.

The acting was great! Big thumbs up to Park Bo Young for playing two totally different characters! Even though I didn't like that much some of Soon Ae's actions, I came to understand and sympathize her. She was the one that brought confidence to Bong Seon. The chemistry between the leads was great!

The OST was so beautiful, especially the one sung by Jay Park! It gave me Michael Jackson vibes.

Rewatch value - 9, it was really good and it had no boring moments. It was great until the last episode.
