In his past life, musician Zack Shelley was framed by his adopted brother Zed Shelley and fiancée Ruby Lewis, left disabled after seven days trapped in a mudslide, and died betrayed by his own sisters. Reborn on the day of the disaster, he is determined to survive and reclaim his stolen life. Despite Zed's efforts to sabotage rescue attempts, Zack endures six grueling days and escapes. He exposes Zed's plagiarism at a pivotal piano competition, but his sisters, Flora and Luna, turn against him even more. Heartbroken, he severs ties with his family. With the help of business titan Whitney Lynd, he defeats Flora in a public contest and unmasks Zed at a high-society banquet. By the time his sisters overhear the truth, it's too late—Zack has already moved on, ready to start a new life abroad, leaving his past behind for good.

Sharon Lucas had two adopted sons, and she had raised them all by herself. One day, she heard that she'd get $5 million relocation compensation for her old house. But her sons accidentally pushed her into the pool when arguing over the money. The next minute, a man showed up and saved her. When the man woke up at the hospital, he had already lost his memory. So, Sharon took him in and gave him the name David. But actually, David was William Lester, the chairman of Lester Group, and he faked the amnesia, trying to investigate Sharon's identity.
