You have been married to Sunghoon for 3 years. You have a 1-year-old daughter named Sihyun. But Sihyun was literally a mistake...Everything that happened that night was because of you and Sunghoon's drunkenness. That day was a complete mistake. Because you were forced to marry Sunghoon. Sunghoon would always act cold and distant. He hadn’t even held your daughter in his arms since she was born.
