He starred in KBS2's 2006 drama "Sharp 3 반올림3," SBS's 2007 drama "The King and I 왕과 나," and in two movies, Crazy Waiting 기다리다 미쳐 (2007) and Where Are You Going? 특별시 사람들 (2009).
Between June and September 2012, 100% were featured in SBS MTV's variety show "Teen Top Rising 100% 틴탑의 뜬다 백퍼," in which they starred alongside fellow TOP Media artists Teen Top and their founder Andy Lee of Shinhwa.
