When the Marquis's house was confiscated, the lonely cousin Shen Yue wanted to fish for koi carp for money, but was rescued by the koi carp. From then on, she and the down-and-out Marquis Gu Jingyan depended on each other. She sold off the belongings of the Marquis Mansion to survive the hardships of three years. When Gu Jingyan overturned the verdict and became a first-rank military Marquis, she only wanted money for her shop to support herself. Little did he know that this feeling of shared suffering had already moved Gu Jingyan's heart, and he guarded him silently all the way. In the end, he exchanged his sincerity for his sincerity. Shen Yue also put aside her worries and joined hands with him, not only guarding the fireworks of the world, but also holding the glory of half her life.
