"Pretty Boy" Jang Geun-seok decides to break up with IU

On the fifteenth episode of the KBS 2TV drama"Pretty Boy", Dokgo Mate (Jang Geun-seok) cried his heart out in front of his beloved Kim Bo-tong (IU).

Mate decided he was in love with her while they were on a date one day and they became a couple.

However, Na Hong-ran didn't let him be. She tailed him with her people to watch his daily routine and when she found out he was going to propose to Bo-tong, she kidnapped and locked her up. Thankfully, she was rescued with the help of Choi David (Lee Jang-woo) and was put in hospital.

Na Hong-ran threatened Mate who called her out of anger and said, "You will go to hell and those around you will be shriveled to death like I did".

Mate was devastated at this threat. He was by Bo-tong's side one night and resisted from putting a ring on her finger. He cried with shaking lips. He got out of the room and said to himself, "Now I know what love is".

Meanwhile, Mate broke up with Bo-tong at the end of the episode with words he didn't mean.
