Joo Ji Hoon and Ji Chang Wook made their first appearance on 'Five Fingers.'

On the 4th episode of the SBS weekend drama 'Five Fingers,' that aired on August 26th, adult Yoo Ji Ho(Joo Ji Hoon) and Yoo In Ha(Ji Chang Wook) made their first appearance.

Yoo In Ha(Kim Ji Hoon) yelled at his mother Chae Young Rang(Chae Si Ra) for not saving him in the fire and saving Yoo Ji Ho(Kang Yi Suk). He stated, "were you disappointed because I'm not a piano prodigy?"

Chae Young Rang was going to kick Yoo Ji Ho out as a way of saying sorry to Yoo In Ha, but she couldn't do so. She had to play the media in order to become the president of Boosung Instruments after her husband Yoo Man Se(Jo Min Ki).

Chae Young Rang secretly brought Yoo Ji Ho who went back to the island. As Yoo In Ha was getting a skin transplant, she became the president of Boosung Instruments. Yoo In Ha successfully received the surgery, but his pinky's nerves died and his life as a pianist also ended.

On the day that his pinky stopped working, he found out about the return of Yoo Ji Ho and their father's death. He yelled at Chae Young Rang saying, "you secretly had a funeral for my dad and Yoo Ji Ho came back without me knowing, and you say that's all for me? Who are you? I don't know you lady," and he went up to the hospital's rooftop.

Yoo In Ha told Yoo Ji Ho who came to him, "don't come close. If you come closer, I'm going to jump," he then attempted to commit suicide. Yoo Ji Ho tried to save him and it showed them 14 years later.

Yoo Ji Ho was fixing a piano and he welcomed Yoo In Ha as he came to visit. The nice older brother and the cold younger brother in the past seemed indifferent. As the adult actors appeared, the drama created curiosity.
