You are hooked In first episodes with the enigmatic storyline. You fell in love with Kim Moo Young but also feels wary towards him.
All the twists and mystery around the 2 main characters keep you in suspense. The passion and the complicated character of the male lead is the most interesting one. It feels real, well written and the scenarists actually did an amazing job to depict such complicated emotions.

Two things made me tick though! When Yoo Jin Gook stabbed Kim Moo Young. When you finally understand how they’re related and what Yoo Jin Gook did to his father, the way he treated him didn’t make sense, and to want to kill him was way out of the picture and didn’t fit the regrets and guilt that he felt.
And then it is how Yoo Jink Kang reacted to that vs how she felt completely desperate when she learned her brother killed Kim Moo Young’s father. It felt strange and also out of place.

We will learn only in the last episode who she really is and how the 2 main characters are intertwined.
Regardless, these flaws, the drama worked for me as the psychology of the characters is really well written and makes you question how you would react in these scenarios. Human beings are indeed complicated animals.
