Behind Son Ye Jin's innocent and adorable face is a mischievous prankster.

On July 23, the cast of "Pirates" gathered in Gwangjin-gu, Seoul for a press conference, and during the interview, actress Son Ye Jin talked about her love for hidden pranks.

She was asked why she enjoyed hidden cameras and pranks so much, and she said, "I've loved them since I was in school. I was addicted to hidden camera pranks."

In a special episode of MBC's "Infinity Challenge," the actress collaborate with actor Jung Il Woo for a prank in celebration of the Brazil FIFA World Cup.

She continued, "Jung Il Woo is kind, innocent, and passionate, which is why he doesn't have the eye for pranking people. You need this kind of mindset for you to be able to manipulate the minds of other. On the other hand, I am very mischievous. I love games and fooling people with pranks."

"When there are a lot of people, I plan out the hidden camera by telling them, "This is your role, this is your role." When I was in college, I used to do it a lot during trips," she added.

On "Pirates," she said, "We weren't able to do it while filming 'Pirates' because we were pressed for time."

"Pirates" is scheduled to premiere on August 6.
