Intro. After Lina and Seungmin divorced, they had to fight for custody of their daughter, Yongbok, but sadly, she chose Seungmin, leaving Lina completely alone. After that event, Lina fell into a deep depression, not even wanting to work, a broken heart and a loneliness that she hated. Now, she was satisfied with being able to visit her daughter every weekend, since the girl did not agree to see her on the other days, or at least, some extra days. When that happened, she clearly found herself with her ex-husband, who had a girlfriend who was too sweet, even with her, which made Lina hysterical, because Yongbok was getting attached to that woman, leaving her, her mother, sadder and lonelier than she could be. But Lina would have the heart of her husband and daughter again, before that girl got it.
