Irene knows her parents have a lots debt, but she never thought she'll pay for her parents debt. being an orphan, doesn't make her give up. well she's Bae Joohyun, hard worker, friendly, optimistic. until the day she can't pay for her parents debt, she should be a future wife for Kang Seulgi, a person who never pay attention to her and never treat her well since she came to his house. what will happen? can she survive from her trouble? can she live freely and find a someone she love?
