During his interview for the magazine, Yoo Ah In shared that he doesn't feel the 19-year age gap between him and his co-star Kim Hee Ae. "Kim Hee Ae is really the exact match of the female lead's image in 'Love Affair's original novel 'Tokyo Tower'... I thought to myself that Kim Hee Ae sunbaenim is really perfect for the role with her image and voice."

"She made a shocking impact even though she revealed her legs in the same way that the actresses who commonly reveal their legs do... I didn't feel any generation gap. She is the best among the actresses who I've worked with thus far."

"After pretending to be older than my age, I feel very comfortable to act like a 20-year-old. I like it even more because I play a 20-year-old who is innocent but not average..."

'Love Affair' will premiere on March 17! Speaking of legs, Yoo Ah In revealed his own in shorts for the chic black-and-white pictorial below!
