Kim is one of the spokesmodels for the brand, along with "Pinocchio" star Lee Jong Suk. He commands some of the highest rates of K-Drama stars for endorsements. In December 2014, his rate had reportedly increased to a range of between $800,000 to $1 million USD for ads, following the popularity of "My Love from the Star."

He is currently starring as Baek Seung Chan in the documentary-style drama, "Producer." During its early episodes, "Producer" struggled with incorporating product placement for its stars, but the series has since developed strong synergistic advertising.

His endorsement power is evident throughout the advertising campaigns of Semir. On June 10, the company uploaded key scenes from the series to its Weibo account, providing further promotion of the actor.

Kim debuted as a television actor in the 2007 family drama, "Kimchi Cheese Smile." He followed the success of supporting role by landing the male lead in the 2008 teen series, "Jungle Fish." He continued to gain popularity, before experiencing meteoric breakout success in the 2011 hit series, "Dream High."
