Lee Jong Suk stars in the movie "Hot Blooded Youth" with Park Bo Young and Kim Young Kwang, and being actors of the same generation, many were looking forward to the friendship they built during filming.

However, it seems that forging relationships during filming is a difficult feat, and Lee Jong Suk said, "There weren't many opportunities for us to become close during filming because we didn't have a lot of scenes together, but I think we became a bit closer during promotional activities."

On his co-star Park Bo Young, he said, "She is very cute and smart. Because of her small frame, I thought she'd be the type to act cute, but when it comes to her acting scenes, she was able to pull off swearing and fighting really well. Even though she's younger, she doesn't seem like it."

"I was born in 1989 and she was born in early 1990, so I thought it'd be a good idea to become friends instead of having an older brother-younger sister relationship. As my way of becoming close to her, I stuck my finger in her nose, but I think it only ruined things," he shared, making everyone laugh.

Lee Jong Suk portrays the role of playboy Joong Gil in the movie.
