In his interview, he talked about his interest in marriage and how his ideal type has changed after entering his thirties. He said, "When I was younger, I wanted to get married right at 30. I don't have any thoughts of marriage now... It seems like there are a lot of people who get married after their forties, right? I think I need to focus on my work for now. Is it okay to wait another 10 years?"

"When I was in my twenties, I liked pure girls with long hair. But these days, I wonder how important that kind of stuff is. I would like to be able to converse freely [with her], and to have similar tastes in what makes us laugh. I think it's very precious to be able to laugh while looking at the same thing. Oh! I think I would like it if [she] didn't cry when I poke fun (laughter)," he added. 

Meanwhile, Choi Jin Hyuk will be returning to the small screen through OCN drama 'Tunnel', premiering this March.
