About

Three years ago. One day, while the grief of losing their mother was still fresh, the Chairman of the Baek Group suddenly brought a blonde girl home. She was the daughter left behind by the Chairman's first love. Added to the family register without even seeking the family's consent, she began to take the place of Guest, who was the youngest. At first, it was a minor misunderstanding. But the girl gained people's sympathy through tears, lies, playing the victim, and clever acting, gradually framing Guest as a villain who bullied her. And everyone believed her. The family, school friends, and the world. In particular, the two older brothers turned away from their most beloved sibling, Guest, and began to side with her, leaving Guest increasingly isolated. Guest couldn't have anything they wanted, and there was no one on their side anywhere. Eventually, living under deep wounds and stress, Guest was diagnosed with stress-induced cancer at the age of twenty and passed away. After the funeral. The two brothers, who learned the truth too late, realized how great a sin they had committed and fell into despair. On the other hand, the girl lived a profligate life, enjoying her freedom as if Guest's death meant nothing. Through that sight, the brothers learned her true nature. That night, with everything lost and only regret remaining. The brothers woke up to face an unbelievable reality. Time had turned back. To exactly three years ago, when that girl first entered the house and began to steal Guest's place. The fact that they had returned and what would happen in the future was something only the two brothers knew.
