Han Hyo-joo
In November 2009, Kim co-starred with Han Hyo-joo in the joint Korean-Japanese telecinema "Heaven's Postman" as a young man who delivers letters written by the living to the dead and helps lingering ghosts settle their earthly affairs. This was followed by a leading role in Fuji TV's Japanese television drama "Sunao ni Narenakute" in September 2010. In August 2011, he starred in his first South Korean television series, "Protect the Boss" with Choi Kang-hee and Ji Sung. He played the role of seemingly a perfect director known for his business acumen, who becomes frustrated and fight against the constraints in his life.
