Meanwhile, Min Ju-yeong made a separate deal with Baek Seok-chun to sell the candy drug in Insung. This deal was made without Kim Yeon-ha. It was also shown that during her childhood, Kim Yeon-ha's friend at the orphanage learned that she was going to be sent to the US. However, the parents were drug addicts, so instead of herself, she sent Kim Yeon-ha, which ruined Yeon-ha's life.

Kim Jong-hyeon informed the team that Golden Bunny was ready to testify against Min Ju-yeong. Meanwhile, Shin Jae-hong was not going to join the team again, as he planned to move to Gangwon and took out a loan from Athletes Support Company.

In the meantime, Yoon Dong-ju and Shin Jae-hong were on a mission when Shin received a message that his loan was disapproved. He left Yoon Dong-ju's side for a few minutes. Yoon Dong-ju was quickly surrounded by Min Ju-yeong's goons, and Oh Jung-gu beat him up.

Oh Jung-gu told him when he was his coach he was aware of his punch-drunk incident and that his optic nerve was so sensitive that if he was hit in the same spot, he might lose his vision. He also told him that he was aware this was the reason why he took the medicines before the match.
