The heroine Qin Shuyan is the "awakened one" in the substitute literature. She spent three years as a stand-in and discovered that the Bai Yueguang in her husband's heart not only looked similar to her, but also had a secret that she didn't know: Bai Yueguang was the heir to a top wealthy family, and her true identity was actually an "invisible competitor" for that inheritance. Her husband uses her as a substitute, not out of love, but to control her emotionally and prevent her from awakening to her inheritance in a mysterious foundation. After the divorce, she used the ancient coin as a primer to activate her dusty true identity - the sole legal heir of the world's largest cultural and arts foundation (Bai Yueguang was just a "stand-in" adopted by her mother from an orphanage to conceal the truth about her inheritance). Then her astonishing talent and wealth were revealed, completely crushing her ex-husband's family, making all his frame-ups seem ridiculous and powerless. After the ex-husband discovered that the "substitute" was the real heroine, he started to chase her crazily, but by this time the heroine had already met the second male lead who truly respected her.
