"When a Man Falls in Love" Yeon Woo Jin's older brother Kim Sung Oh faces Lee Chang Hoon as soon as he is released from prison and leaves a lasting impression.

The 5th episode of the MBC drama "When a Man Falls in Love" featured Lee Chang Hee (Kim Sung Oh) being released from serving time in prison for committing murder.

When Han Tae Sang (Song Seung Hun) gives Lee Chang Hee a credit card to go buy a nice suit, Koo Yong Gap (Lee Chang Hoon) shows up. Lee Chang Hee falls into the trap Koo Yong Gap had planned and ends up being taken to the police station for violence and damage property.

Koo Yong Gap states that he will let Lee Chang Hee off the hook if Han Ta Sang gets down on his knees to apologize for Lee Chang Hee's violence as well as the death of the previous boss.

Lee Chang Hee had used violence on Koo Yong Gap because he was being insulted for committing murder for Han Tae Sang to put his little brother through school. Lee Chang Hee raised the tension of the drama as soon as he reappeared in the story and drew attention.
