On the day of her grand wedding, Gu family young master Gu Yanchen delayed the auspicious hour three times to protect his dependent cousin Liu Rumei. Seeing through his bias and heartlessness, Su Wanning immediately remarried her childhood sweetheart, Major General Lu. Gu Yanchen realized it too late and deeply regretted his actions, while Liu Rumei's true face was also exposed. Under Lu Zheng's protection and respect, Su Wanning carefully unraveled the arms procurement conspiracy behind the wedding, not only tearing down the green tea and slapping her ex in the face, but also steadily securing her position as the mistress of the Lu mansion, achieving a legendary romance in Beijing's upper circle.
