Catalpa, you're right. Koreanwiz uses that picture on her "Who's My Love" page, and so I'd seen it before. I think it's the hair. He used to wear it that way (like a NORMAL person, LOL) at the beginning of the show, before he and Sangsik made their pact with Satan's hairdresser and started wearing their combed-forward, fluffy "Caesar" style.
He does photograph better than he, er, "movies" I guess. What I love about that picture (aside from the fact that it's appealingly posed, like friends out together getting photographed by a tourist) is "Ji-yeun"--isn't she adorable! Like a pixie.
