Li Man is Jiang Yicheng's ex-girlfriend. Like Jiang Yicheng, Li Man is also a programmer. When the company was founded, they had a very good relationship. But in the end, Li Man betrayed Jiang Yicheng, and Li Man and other companies almost let Jiang Yicheng's company go bankrupt. Jiang Yicheng encountered such a thing at the beginning of his business, which was a great blow to him, and he liked his girlfriend Li Man very much at that time. He didn't expect the girl he liked to do such a thing.
After Li Man left, Jiang Yicheng suffered a great blow, so he made a rule for the company not to recruit female programmers in the future. Jiang Yicheng was afraid that the story with Li Man would be staged again, so he solved the problem from the root. Li Man returned to China after the story was broadcast for a period of time and has been close to Jiang Yicheng. Jiang Yicheng knew how stupid his original behavior was. Jiang Yicheng has slowly forgotten Li Man. When Li Man apologized, Jiang Yicheng didn't forgive her. Li Man finally lost her career and love.
After returning home, Li Man has been trying to get back together with Jiang Yicheng, but at this time Jiang Yicheng has married Lu Li. Facing the return of his ex-girlfriend, Jiang Yicheng has also wavered. Jiang Yicheng always wanted to make up for the regret with Li Man before, but after thinking about it, he found that he had long disliked Li Man, but he just had an obsession in his heart. Jiang Yicheng fell in love soon after he met him, and the appearance of Li Man also made Jiang Yicheng's relationship in crisis.
After learning of Li Man's existence, Li Lou became particularly sensitive. He often worried that Jiang Yicheng would abandon himself and get back together with Li Man. Jiang Yicheng was afraid of Lu Li's misunderstanding and secretly went to find a man in Li See, but the two did not rekindle their old love. Jiang Yicheng found that he liked Lu Li and chose to live in peace with Lu Li.
