When I first went to watch this one, I was a little hesitant. I saw all these people talking about how well it portrays mental illness and the such. I figured I probably wouldn't like it because it would be too sad and depressing.

I'm glad I decided to give this a chance anyway, because it is really amazing.

This is the third drama I've seen where Gong Hyo Jin was the female lead, and I was really surprised. The other two dramas I've seen her in were Pasta and The Greatest Love. Her characters in those were so different than in this one and it was nice to see. She is really a great actress, and I feel she really brought her A game here as well.

The male lead was played by Jo In Sung, this is the first time for me to see him act and at first I wasn't a huge fan, but slowly came around as the drama progressed. He did a pretty great job.

The story and characters are really well done, and this might be one of the only dramas I've seen where everyone kind of felt like real people. People with faults and strengths that seems more real than usual. I really like how this drama's pacing had the viewer realize what was going on first, then the other characters, and then finally the main person. It really kept you in anticipation since you found out what was going on first through clues. Then the focus of the drama isn't just a love story anymore, it's watching these characters slowly realize what you found out. Then it's watching these characters deal with it in their own personal ways.

This one right here is definitely going to be a classic down the road. Where people with look back fondly at this and say how great it was.

This drama was amazing and I highly recommend this drama.
