- Nam Yujin, who lost her parents as a child, grew up with the three brothers of the Namjin Group. She promised to marry one of the three brothers on her birthday when she became an adult. One day, Nam Su-a, the long-lost youngest daughter of the Namjin Group, appears, and Nam Yujin becomes estranged from the three brothers. Falling into despair, Yujin impulsively decides to marry Ha Jihun of the Hawon Group, who has had a crush on her for a long time. The three brothers think Nam Yujin is lying just to get their attention. Now, the three brothers of the Namjin Group only care about Nam Su-a, regardless of whether Nam Yujin gets hurt. Nam Su-a is not satisfied with just monopolizing the brothers' love; she tells them she wants the mementos of Nam Yujin's parents that appeared at an auction and has them buy them. When the brothers' attention shifts to Nam Yujin, she pretends to have heart pain even when she isn't sick to receive love. ----- Detailed Description ----- Nam Yujin grew up in an orphanage before entering the Namjin household, where she experienced the form of a family for the first time under the care of three brothers. When they were young, the brothers jokingly made a promise that Yujin would choose one of them to marry on her 20th birthday, and that promise remained with Yujin as "the reason I won't be abandoned by this house." As time passes and Yujin approaches adulthood, the family begins to pour all their attention onto Su-a, claiming that their long-lost biological sister, Nam Su-a, has returned. After Su-a arrives, the rules of the house change. Yujin's room is given to Su-a, her belongings are moved to the guest room, and Yujin's tastes and traces are erased one by one because "Su-a dislikes them." Even if Yujin is sick with a high fever, the brothers brush it off, but if Su-a suffers even a minor scratch, the whole house acts as if it's turned upside down. Su-a makes Yujin clean, breaks things and blames Yujin, and the brothers force Yujin to apologize every time. Meanwhile, there is something Yujin must reclaim. Circumstances arise where her parents' keepsake necklace appears at an auction, and Yujin enters the auction house with all her savings. However, even at the auction, the brothers pour money into Su-a, telling her to "say whatever you want to have," and treat the moment Yujin tries to protect the necklace lightly. In the end, Nam Jaeyoung wins the bid for the necklace. -- Create the story that follows!!
