It's a movie with a simple premise and a well-known cast. We have to praise Yoo In Soo's consistently exceptional and well-developed performance as the villain in this film. Everyone knows that this actor usually plays comedic roles, but whenever he portrays villains, he transforms himself. In other words, he's an actor with great stage presence who can seamlessly transition from humor to drama and vice versa.

Now, it's necessary to mention that Yoo Sun Ho's performance as the film's protagonist is very lacking and stiff. It seems like he's holding back. He portrayed a very monosyllabic and emotionless protagonist.

The film has its flaws, for example, what's the backstory of Da Young's "stalker friend"? In three minutes, that could have been explained and developed. It felt somewhat random. What's the significance of that epilogue? What important post-film finale factor does that scene have?
