I was surprised by how I actually enjoyed watching this drama. It's sad and not very original, but the lead characters were so sweet that I didn't really mind.

I was curious about Shim Changmin's acting and wasn't disappointed. He looks so young and his character is very endearing, if a little gloomy, so the experience of watching him in a drama was nice. The lead actress,
Moon Ga Young, was perfectly cast, too. The age difference between them didn't bother me because it makes sense for the story, and Changmin's characterization as a high schooler was perfectly believable. He really did look 15 years old.

There isn't much to the plot, though. The 4 episodes are fairly repetitive and there aren't many plot twists, so you can easily guess where the story is going. The music is nice, the leads have chemistry, and the episodes were well produced. If you aren't looking for a drama that's more complicated and happy, then this drama should be fine. It's not remarkable, but I didn't think it was bad at all.
