I'm really into this series. This drama is just on another level. I really enjoy all of the emotion in every single episode (I literally cried a lot watching this series). Like chocolate, this drama is full of bitter-sweet emotion. The plotline is so fresh and interesting, chemistry between the main cast is so amazing, and almost all the cast did a very good job at portraying their characters. The ost are also good. So perfect overall. It's hard to find an emotional yet so beautiful series like this. It's one the best melodrama I've watch so far. Definitely worth to watch. Highly recommended!
