The Innocent Man

The Innocent Man is a 2012 South Korean television series starring Song Joong-ki, Moon Chae-won, and Park Si-yeon. It is known on Netflix as Nice Guy. It is a dark melodrama involving betrayal and romance. It aired on KBS2 for 20 episodes from September 12 to November 15, 2012. Synopsis Smart and promising medical student Kang Ma-ru (Song Joong-ki) is deeply in love with his slightly older neighbor Han Jae-hee (Park Si-yeon), a television reporter. But when her situation takes a turn for the worse and Jae-hee becomes desperate to escape poverty, she meets a man who changes everything—a rich CEO who introduces her to a life of comfort. So she turns her back on Ma-ru, choosing money over love. The brutal betrayal leaves Ma-ru fractured—not just angry, but a completely changed man. A few years later, Ma-ru is now 30 years old and works as a bartender and gigolo, no longer a "nice guy." He then meets Seo Eun-gi (Moon Chae-won), a young chaebol heiress who's being groomed to take over her father's conglomerate. Eun-gi is cold and calculating, business-savvy, and raised by her father to never show emotion to anyone.
