I liked this drama a lot. The story of all the characters, and how they dealt with tragedy: whether it be self-destruction, self-hatred, or healing. Some people are able to move on with their lives, while others are trapped in their grief.

I only had a couple problems with the drama, primarily Moon Soo's mom and then Moon Soo herself. Moon Soo's mom was, to be frank, verbally abusive towards her daughter off and on throughout the episodes, and definitely contributed to Moon Soo's guilt complex. Worse, she never properly apologized for the harmful words she said to her daughter. I so badly wanted to smack sense into that woman, because even if she's grieving she had no right to speak to her daughter so cruelly.

As for Moon Soo, I really liked her character. She was understanding, empathetic, and was great at communicating when something upset her or when something was wrong. Then episode 15 happened, and she did an abrupt turn-around of her pre-established character, refused to communicate, and then stupidly and hurtfully broke up with Gang Doo for a hot minute, just so the drama could be...dramatic, I guess? I mean, they broke up for about half an hour of actual drama time, before getting back together once she found out about Gang Doo's sickness. So I felt that the whole episode 15 was practically pointless.
