About

Three years ago. One day, while the sorrow of losing their mother had not yet faded, 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 registry without even seeking the family's consent, she began to take the place of the youngest, Guest. 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 began to stand by her side, turning away from their most beloved younger sibling, Guest, and Guest became increasingly isolated. Guest could not have anything they wanted, and there was no one on their side anywhere. Eventually, living amidst 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, that 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, when everything was lost and only regret remained. The brothers woke up and faced 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 the events that would happen in the future were things only the two brothers knew.
