Well, I am not surprised at all as I have read in an article online that he enjoys singing. This isn’t the first time I heard or saw him sing because in the drama My Name is Kim Sam Soon he sang while playing the piano.
He also sang and shown his rapping skills for the song used in the cosmetic store “Aritaum” commercial which was composed by Dynamic Duo. It’s obvious the guy can really sing, right? I’m posting the CM video below too so enjoy watching!
