Ming Yao's battle with severe insomnia had been fatal in her previous existence. Upon reincarnation, she awakens beside a temperamental tycoon who immediately demands separation, thrusting divorce documents into her hands. Without hesitation, Ming Yao complies—only to discover within a single night that she cannot escape her affliction. The insomnia persists relentlessly, impervious to any pharmaceutical remedy, yet she finds unexpected solace in a single cure: the steady rhythm of Gu Siye's breathing beside her. The world observes Madam Gu as a devoted wife, believing she cherishes her husband despite his cruel treatment and daily torment, never suspecting the truth behind her devotion. Everything changes when Ming Yao finally formulates a medication for her insomnia. At an exclusive banquet, she appears radiant on a famous actor's arm before presenting Gu Siye with unsigned divorce papers once more. "Mr. Gu, consider us even. Our connection ends here." In response, Fourth Master Gu destroys the documents immediately, cornering her with piercing intensity. "Leave if you wish, but first return what belongs to me." "What exactly did I take?" she challenges. "My heart," he responds with fierce possessiveness. Whispers of ridicule follow Ming Yao—accusations of incompetence and shamelessness flood high society, anticipating her dismissal. Scandal erupts when media sources claim she's involved with the world's foremost tech genius. The hacker swiftly denies this, declaring her his mentor instead. Days later, paparazzi photographs place Ming Yao at the same venue as a renowned luxury fashion creator. The designer immediately clarifies their true dynamic. Witnessing seemingly endless romantic entanglements surrounding his wife, Gu Siye's jealousy ignites. He silences her with a fierce kiss, publicly staking his claim: "Mrs. Gu is mine alone. Anyone spreading falsehoods will answer to me."
