The story needed some improvement - ep 8 was completely unnecessary and the first few episodes were extremely depressing. Debtor is a depressing job, nothing romantic about that for me.

The best part of this show was the kissing, thank you for real and intense kisses. I felt the emotion in those scenes.

The music was great but my biggest problem with the show is I WANTED DANCING!! I wanted to see a full routine, not fake snapshots. I was hoping the dancing would play a more central role, and I was very disappointed.

Other issues - running through snow with no shoes? Getting out of a car that he's driving to run all the way back home? Breath fogging indoors suggesting it's freezing inside? What happened with Hyeong's job at the end? Why didn't we get to see the villain's reaction in the end? What's the truth about Shi On's mother?
