Kwak Dong Hyun expressed his anger towards his father Choi Jae Sung.
On the 2nd episode of KBS 2TV Wednesday/Thursday drama "Generation of Youth" (script Chae Seung Dae, director Kim Jung Gyu) broadcast on January 16th, Shin Jung Tae (played by Kwak Dong Hyun) was upset at his father Shin Yougn Chul (played by Choi Jae Sung).
On this day, Shin Jung Tae got spending money from Poong Cha (played by Jo Dahl Hwan) after getting into the Dobi gang proposed by Hwang Bong Shik (played by Yang Ik Joon) and bought food to bring home.
Shin Jung Tae came home feeling great and learned through Kim Ok Ryun (played by Ji Woo) that his younger sibling Shin Chung Ah (played by Lee Ji Woo) was in the hospital as he was shocked.
Shin Jung Tae ran to the hospital right away and held Shin Chung Ah's hands saying how sorry she was as she bawled and changed faces as soon as she saw Shin Young Chul's face.
Shin Jung Tae grabbed Shin Young Chul and said, "Who's the father? Do you know how many times I've seen you? Just three times after I was born. When mother died, Chung Ah was sick and where were you when I was heart broken? What kind of father is this?" he poured.
Shin Jung Tae was about to hit Shin Young Chul in the face and stopped saying, "Just leave us alone. If you put your face into Chung Ah, then I'm not going to be okay. I might kill you" and showed how angry he was to his father.
