劉亞仁
Song's breakout role came in the fusion historical drama "Sungkyunkwan Scandal" where he played the role of an 18th-century Joseon-era rich, indolent playboy. Despite stable but unspectacular ratings, the drama became a cult hit and his on-screen "bromance" with actor Yoo Ah-in was popular with viewers. Song also joined the cast of variety program "Running Man" from 2010 to 2011.
