[All] The man who wears the shirt best in the world is Jeong Seong-chan

He's just wearing a shirt and glasses, but where does this cool vibe come from? It looks like a casual photo, but it looks like a pictorial, and if you keep looking at it, it looks like a scene from a movie. He's wearing a shirt and glasses, so he looks like an office worker. Where can I find someone like Sungchan at work?
