Months after, Dong Kook is happy with his retired life. His family lives abroad. Meanwhile, Woo Hyun tries to find his own cure.


The cast was a solid choice for this seven-episode series. Both Sung Dong Il and Lee Seo Jin played their parts really well. Lee was exceptional in portraying both the psychotic murderer and the grieving father. However, he maintained a glint in his eye throughout that signaled an evil side of him that did not go away.

Trap was a crime thriller that was fast-paced but each moment counted. Even though they only had seven episodes, They maximized the time and laced the story well. The buildup to the climax was well-executed. The twist to Woo Hyun’s real personality and motive was also a good surprise.


While this isn’t a drawback for me personally, this might not sit well with others who are sensitive. The drama was gruesome and some scenes were horrendous even if they were blurred out. Sensitive viewers may not stomach the scenes well as it was a bit too violent.

I feel a bit unsatisfied with the ending because spoiler I wish Woo Hyun would have been sent to jail. In fact, it seems that no one was imprisoned. Considering the murders, the killers also died.
