Yoon made his first foray into digital filmmaking with "I Am Happy", adapted from the novel "Mr. Cho Man-deuk" by Lee Cheong-jun. He shot the ironically titled romance film on HD for six weeks, and cast Hyun Bin and Lee Bo-young as a megalomania-afflicted patient and his nurse who find more comfort inside a psychiatric ward than their reality outside. "I Am Happy" was the closing film of the 13th Busan International Film Festival in 2008 and was released in theaters in 2009.
