Kim Woo Bin said, "We actually drank before filming the scene. Kang Ha Neul needed to really make it seem like he was drunk so we decided that we will drink beer before going into filming to get into that mood."�

The scene was when Kang Ha Neul, Kim Woo Bin, and Junho are drunk inside a karaoke room, singing their hearts out just like any other boys in their early twenties. Details of the scene can be seen when the movie releases.�

When it came to talking about drinking, actor Kang Ha Neul shared his special experience as he revealed that soju was the only thing he needed to make him feel better when he was 20 years old.

He said, "At the time, everything was okay as long as I had soju. I was in theater when I was 20 years old, and there were a lot of hardships and things that hurt me. It was a time when I was learning how to deal with others."

The actor added that he would drink to open up to senior actors and form relationships with them the night before his performance.�

Meanwhile, the movie 'Twenty' will premiere in theaters on March 25!
