Lan Zhi, a flower season girl from the capital, fell in love with the Crown Prince of the country. However, due to the Crown Prince's inability to marry her as his legitimate wife, he swore not to marry her. In order to marry her, the Crown Prince promised his mother to marry the daughter of the Prime Minister's family, but on the condition that Lan Zhi enter. Nevertheless, Lan Zhi still refused to marry, causing great injustice to the Crown Prince. Lu Siyu, who had received help from Lan Zhi since childhood, heard that Lan Zhi was planning a husband, but no one came to propose marriage. He, who had been silently in love with Lan Zhi, transformed into a drunken immortal accountant and came to his door. Lan Zhi did not mind poverty and love wealth, and readily agreed. From then on, the two of them lived a life of mutual respect. However, without obtaining the crown prince of Lanzhi, it was difficult to treat her well with a wife who was as gentle and generous as a flower at home. Instead, she repeatedly harassed Lanzhi's peaceful life, not only sending people to beat up Lu Siyu, but also causing him to be fired. In the end, she even tied up Lanzhi. Lu Siyu found out and rescued Lanzhi, fleeing to an unknown place to start a new life... Years later, Lanzhi had a child, and the crown prince had not forgotten her. When someone was sent to search for the whereabouts of their family, Lu Siyu died to save Lanzhi. Lanzhi had no choice but to agree to marry the crown prince, but in fact, she was pregnant. When he relaxed his vigilance to seek revenge for his husband, Lan Zhi finally avenged her and ascended to the throne with her own son
