Hateful But Once Again (2009)

Han Myung In (Choi Myeong Gil of Young Love Jae In), CEO of the successful Myungjin Group, and her husband, vice president Lee Jung Hun (Park Sang Won), seem to have it all - fame, money and a perfect family - until Han discovers an illicit relationship between her husband and top actress Eun Hae Jung (Jun In Hwa, Baker King Kim Tak Goo). Eun, who strongly believed that she was Lee's true love, is devastated when she finds out that Lee will no longer see her and has decided to support his wife Han. Further complications arise when Myung In's playboy son Min Soo (Jung Gyu Woon, History of a Salaryman) is arranged to marry "good girl" Choi Yoon Hee (Park Ye Jin of My Princess), and they discover their twisted fate as well.
