Instead of a drama, this show felt like a long movie. I was hooked onto it and kept watching the back stabbings, twists, and turns unfold. This drama shows us how greed controls many, but even so, human morals may still prevail at the end. Yoo Seung-ho was fantastic in this drama in the way he portrays his emotions as a kid and then adult. Park Min Young was criminally underused, but her role was still very appreciable. I really enjoyed the friendship between the two leads but also didn't mind how it blossomed into romance near the end. The side characters were developed, but many relationships between them are unknown. This may be the first drama where I really wished that a bit of K-drama unrealism filled in and gave our ML a miracle cure for his disease. The ending is so bittersweet with all the antagonists being finally put to justice. The OST did its job with the appropriate scenes.
