As soon as I started this drama I couldn't stop watching. The story was something else and always kept me on edge; with the male lead's suspicious and mysterious personality and the female lead's very relatable character. By the end of it I started getting really scared as of how it's gonna end because I read a lot of disappointed reviews. Thankfully though, the ending was good, in my opinion ofcourse. The cast was amazing and the acting was so so good!! I fell in love with baek in ha's crazy personality and weird facial expressions. The actress really took the role to a new level! :D I pretty much liked how realistic the story was from beginning to end. It's safe to say that I haven't watched a korean drama that was similar in anyway to this before. I highly recommend it. It is not a waste of time, and you'll enjoy every second of it.
