He thought she was a thief | Bad Love

So-Won (Shin Go-Eun) is 29-years-old and has a high school level education. She works as a clerk at a fabric store. So-Won possesses a bright and honest personality. Her dream is to become a designer. Her twin sister is Eun-Hye (Cha Min-Jee). Eun-Hye's personality is completely different from So-Won's. Eun-Hye is feminine and quiet. Both sisters were accepted into a university, but, due to their financial situation, only Eun-Hye was able to attend. To this day, Eun-Hye feels guilt about that.

Jae-Hyuk (Lee Sun-Ho) works as a designer. He is the first son of Chairman Han (Nam Kyung-Eup), who runs the Noyoo Group. Jae-Hyuk fell in love with Eun-Hye at first sight and they live together despite objections from Jae-Hyuk's family.

Jae-Hyuk has a younger stepbrother, Min-Hyuk (Yoon Jong-Hwa). Min-Hyuk desperately wants to receive recognition from his father. Meanwhile, Yeon-Soo (Oh Seung-A) works as a contract employee at Noyoo Group. When she was little, she lived off So-Won’s family. She wants to have successful life, but, in reality, she is still poor.
