I'd been eagerly waiting this drama with high expectations, and I can say it was worth the wait.

To start, the acting was magnificent. The casting was great, especially Yoon Se Ah and Kim Byung Chul (aka Sky Castle couple), with excellent chemistry. The rest of the cast did a great job too.

As for the story, I enjoyed it, despite a few plot holes (like how Hyun Woo knew Su Yeon’s other phone number, or the sudden friendship between the cop and Hyun Woo.) The plot twists were truly shocking with unexpected turns in every episode that kept me hooked. Sometimes, I was so blown away that I couldn’t even come up with a theory about what might happen next. The ending was a bit weak, but it wasn't a total disaster.

The music was also really cool. It used classical instruments that went perfectly with the story and made it feel really elegant. I loved that.

Overall, I found this drama to be highly enjoyable. Even though some small details were left unresolved and the ending felt a bit lacking, it was definitely worth watching.
