Gu Yanzhi is the heir of Marquis Weiyuan, a nobleman who has just returned to the capital from a three-month southern inspection tour. He is married to Shen Weiyang but has always been emotionally distant, focusing his attention on his visiting cousin Rong Wanqing and the daughter of Prince Zhenbei, Su Luoxue. Though he feels a faint fondness for his wife, his repeated neglect and prioritization of others lead to a tragic miscarriage that Shen Weiyang suffers alone. After discovering the divorce letter, he desperately tries to win her back, first by punishing Rong Wanqing and then by proposing a one-year trial period, but his efforts only make her more determined to leave. He is torn between his duty, his feelings, and the consequences of his past actions.
