38-year-old Maren suffers amnesia in an accident, waking up with only memories from her 21-year-old college days. She's horrified to find herself living in a mansion, her husband Rook cold and distant. As fragments of her memory surface, she sees the truth: for years she gave up everything for Rook, severing ties with her best friend Faye and blocking her senior, Gray. Rook had been having an affair with Liora and had a daughter, Brinley. Even more heartbreaking, Brinley had been bullying her daughter, Tora, with Rook not only siding with her but also publicly belittling and humiliating her. This time, Maren refused to tolerate it. She calmly gathered evidence of Rook's asset transfers, hired lawyer Gray, decisively divorced him, cleanly reclaimed her and her daughter's assets, and received a substantial settlement. After the divorce, she apologized to Faye, rekindled their precious friendship, and finally understood her own heart, accepting Gray's advances. Unexpectedly, Rook, enraged by losing everything, kidnapped his own daughter, Tora, to blackmail Maren. After Tora was rescued, Rook and Liora were arrested by the police. In revenge, Brinley not only set fire to Faye's office but also attempted to run Maren over with her car. At the critical moment, Gray stepped in and saved Maren. Ultimately, Maren, holding her daughter Tora's hand, walked alongside Gray towards a new life. She finally understood that true rebooting wasn't about regaining memories, but about finding herself.
