“There’s no limitation to what role I can play. I will do whatever and build my experience. But if there is a genre I would like to try one day, it’s noire. I’m known as a ‘sweet guy’ because of past characters, but I think I’m a tough guy. I think I can appeal as a manly character.”

“While filming [Lovers of the Red Sky] I had the feeling that the drama would be really interesting, and I worked hard to prepare for it so I was secretly expecting a lot. Thanks to all of the love that so many people gave to the drama, it was able to come to a meaningful end.”

“Since I’ve lived with Ahn Hyo Seop before, we’re close and know a lot about each other. Throughout filming, I was really thankful to Gong Myung for various reasons. Since we got closer, I think we were able to have even better teamwork.”
