This drama has climactic episodes! I had to pause to satisfy some intense excitement. I've read some comments It's about love's trial and tribulation. The plots build on one after another. No fast forwarding. The flash-backs were kept to the minimal, where at some points it helps to have the playbacks. There are a few good songs and satisfying ending to the story. This drama follows the Heavy Sweetness, Ash-like Frost in similar ways but not the same story. The ending is satisfying. Definitely a re-watch.
