In front of the General Lee Soon Shin (Yoo Dong Geun), Choi Kang Chi bursts out in tears. Choi Kang Chi says, "The people who were the only remaining family members.... Deserted me. They called me a beast!"

Lee Soon Shin replies, "People always get hurt the most by the people who are the closest to them. You get hurt and scarred because they were someone you loved and cared for. It is not important how other people see you. How you view yourself is the only important thing."

Choi Kang Chi yells at Park Tae Seo to look him in the eyes but he is unable to look at him in the eyes. Choi Kang Chi says, "Why aren't you looking at me in the eyes, what are you scared of? Please look at me Tae Seo! You have to look at me in order for me to show you my real self!"

When he looks into Choi Kang Chi's eyes, Park Tae Seo begins to punch him. Choi Kang Chi does not attack but simply block his punches with his body. Park Tae Seo stops and Choi Kang Chi says, "That's right, you're supposed to face your friends like this Tae Seo!" He then hugs Park Tae Seo tightly and begins to cry harder.
