I'm happy I watched this drama! The title seems very cheesy (as many kdrama titles do) so I wasn't expecting anything too great. However, I was pleasantly surprised right off the bat when it turned out that the main character was visually impaired. Personally I have never seen any representation for the visually impaired in kdramas, so for me this was a big plus (spoiler: even though it doesn't last for the whole drama).
Moreover, this drama has many characters with heartening character development. Especially the female lead goes through some significant changes, but also side-characters like Archangel Hoo are fun to watch throughout the whole drama. Speaking of side-characters, I really loved both Jung Yoo Mi and Hoo. Great casting for the leads as well as the side-characters.
Furthermore, the main romance was, in my opinion, very believable. I could really feel that they cared deeply about each other. I've also never seen a kdrama where they kiss quite as much as they do in this one (not that that's super relevant, but still something that stood out to me).
The story was also interesting, it's cheesy, tragic, lighthearted and extreme all in one. However, it took a really long time to get to the main event of the story, the dancing. I feel like this drama could've easily been 12 episodes. Nontheless, I enjoyed it, even though the last few episodes didn't grab me as much as the first 3/4th of the drama.
The biggest thing that annoyed me about this drama were the 'villains'. They were poorly written and didn't feel like fully fleshed-out characters. Especially Choi Young Ja felt extremely empty and her scenes were simply hard to watch. Geum Ru Na was slightly better but still felt very empty. Ji Kang Woo also annoyed me a lot of the time. He was way too persistent in pursuing Yun Seo.
But overall I enjoyed this drama and I'm glad I watched it. The backstory of the main characters is very interesting too. I believe this drama has a little something for everyone!
