SEE ALSO: Seolhyun shares heartwarming moment with youngest fan in Gangneung

During their interview, the lead actors and actresses of the film, including Kim Nam Gil, AOA's Seolhyun, Seol Kyung Goo, and Oh Dal Soo, briefly introduced their characters. Actors Kim Nam Gil and Seolhyun were then asked about their romance in the film despite their 15-year age difference. 

Seolhyun began, "[Kim Nam Gil] would be so nice normally, but once filming began, he became 180 degrees different. So I thought, 'Wow, scary.' But once I felt that way, even when he smiled and laughed easily off the cameras, he felt scary to me," making the other actors laugh!

Kim Nam Gil then put his two cents in, stating, "When I first heard about the casting, I felt burdened. [Seolhyun] was perfect as Seol Kyung Goo's daughter, but as my girlfriend, it felt burdensome, and I conferred with director Won Shin Yeon. On set, it turned out my mental age is young, so we got along." 

You can catch these actors in 'Memoir of a Murderer' when it premieres this September!
