After many years of separation, Du Luoyue has lost her memory to her first boyfriend Jiang Xian, and no longer remembers people and things about him, but the amnesia came without warning, and no one around her knew about it, including herself. So when the two met again, Jiang Xie harassed Du Luoyue in every way, and Du Luoyue, who had lost her memory, had no choice but to send Jiang Xie to the police station as a pervert, which also changed Jiang Xie's fate.

Therefore, it attracted Jiang Xian's revenge, but he accidentally found that Luo Yue really had amnesia, so he turned his revenge to a sweet pet. Luo Yue also fell in love with Jiang Xian again, when the two were sweet, the visit of her legitimate boyfriend Zhang Chaosheng for many years, Luo Yue was ashamed of her boyfriend, Luo Yue decided to marry Zhang Chaosheng!

In an emergency, Jiang Xian started to restore Luo Yue's memory, which also triggered the emotional entanglement between Luo Yue's best friend Jin Wei in college and Luo Yue's crush Gao Fan, as well as her current best friend Yaoqing, her male best friend Shi Jie, and Jiang Xie's friend Song Zanghai.......

After three years of hard work, Du Luoyue, a talented woman from the journalism department of a well-known university in China, has been promoted from a small planner to a key account manager of the camera division of DK Group. Not long after he was promoted and raised, he met his super capable first boyfriend Jiang Xian when he was on the first big project in his life.

But more than three years ago, Du Luoyue was heartbroken due to a breakup, drenched in a heavy rain, and the fever was not treated in time and left sequelae, resulting in fragmentary amnesia, this memory happens to be all the people and things related to Jiang Xian!

After many years, the two met again, and she no longer remembered him. Since it was a business meeting between the two, Jiang Xian always thought that Luo Yue was deliberately avoiding him, so he was desperate to pester her, crazy like a pervert.

As a result, on the eve of signing the business cooperation contract, Du Luoyue was found to be tracking him, and Du Luoyue sent him to the police station as a pervert. Jiang Xian lost his career and fell in love because of this, and he went to Beijing to find Du Luoyue in grief and anger to ask for the reason for framing him.

In despair, Jiang Xian temporarily lived in the house of Song Zanghai, a college classmate who had nothing but a skeleton, and Song Zanghai's mother-in-law and mother were not at all like the old Beijing natives!

The world is very big, but you don't remember me when I am in front of you! The world is also very small, and when I hate you, you live next door to me! Unfortunately, Du Luoyue and Song Zanghai happen to live in the same community, the same building, and the same floor! But as neighbors for many years, Du Luoyue, who went out early and returned late, and Song Zanghai, who was black and white upside down, never met, and only found out when Jiang Xian moved in.

In order to seek an explanation, Jiang Xian repeatedly harassed Du Luoyue, and Du Luoyue called the police many times to no avail. Because when he was arrested for the first time, the presiding officer Huang happened to be Fa Xiao in Song Zanghai Hutong, and later the three became friends. As a result, the Huang Police Station refused to hear Du Luoyue's police on the grounds that it was difficult for the Qing officials to decide family affairs!

After hitting the wall many times, Jiang Xian accidentally found that Luo Yue's fragment was amnesia! So he no longer pursued the past, listened to the opinions of his friend Song Zanghai, changed the hard encounters in the past, slowly contacted Du Luoyue, and began to sweetly pet her!

Just when the two fell into sweetness, Du Luoyue's official boyfriend Zhang Chaosheng came to Du Luoyue's city on a long-term business trip! This made Jiang Xian, who loved her deeply again, heartbroken, and decided to ask the help of his doctor friend Song Zanghai to restore Du Luoyue's memory! But to recover this memory, you must know the cause of amnesia, otherwise it will only add amnesia blood clots to the brain!

So Jiang Xian found Du Luoyue's best friend Jin Wei and mutual friend Gao Fan from college to ask Du Luoyue about the reason for Du Luoyue's amnesia, but neither of them knew about Du Luoyue's memory loss. But through the understanding of this trip, Jiang Xian also unexpectedly learned that his friend Gao Fan fell in love with Luo Yue at first sight and had a crush for many years! And everyone knew about this matter except himself, including Gao Fan's current girlfriend! This made Jiang Xian realize that the three of them were in the same school, but they had never gotten together for four years!

Jiang Xian searched everywhere for the cause of Luo Yue's amnesia and returned, but received the news that Luo Yue planned to marry her boyfriend Zhang Chaosheng! He fell into despair again, he gave up his future, gave up his girlfriend who had been with him for many years to come to the capital to find her, but in the end she wanted to marry someone else!

Impulsively, Jiang Xian decided to tell Du Luoyue that she had lost her memory, and let her know that she had fallen in love with her again, hoping that she would not be deceived by the so-called genuine boyfriend in front of her! So he took Du Luoyue out of Beijing, back to Wuhan, and back to the place where they started! However, this move was discovered by Zhang Chaosheng, and he misunderstood Luo Yue's P-legged neighbor Jiang Xian! But Zhang Chaosheng loved Du Luoyue deeply and did not dare to blame Du Luoyue! For fear of hurting the relationship between them!

So Zhang Chaosheng decided to seek Jiang Xian to fight alone, Jiang Xian deliberately did not inform Zhang Chaosheng about Du Luoyue's amnesia, but deliberately let Zhang Chaosheng accidentally discover that Jiang Xian was Du Luoyue's first love, not himself. But Jiang Xian never expected that Du Luoyue always thought that Zhang Chao was his first love, and later those who knew her thought that Zhang Chaosheng was Du Luoyue's first love, and the two had been in a different place for many years, but their relationship was not light. Because Du Luoyue felt that she only loved one person in her life, that was Zhang Chaosheng, and she didn't have anything to do with herself!

It was precisely because of Du Luoyue's insistence that Zhang Chaosheng let go of his past mustard for Du Luoyue and officially proposed to Du Luoyue. At the proposal banquet, Jiang Xian kept mischievous, but he still couldn't stop Du Luoyue from accepting Zhang Chaosheng. The unwilling Jiang Xie continued to sabotage Du Luoyue and Zhang Chaosheng's parents' meeting dinner, which also made Jiang Xie unexpectedly know the reason for Du Luoyue's amnesia!

But recovering this memory requires the assistance of a former friend, so Jiang Xian spends a lot of effort to destroy Gao Fan's current relationship and force his girlfriend to break up with him! And invite Jin Wei and Gao Fan to Beijing to work! During the period of secretly helping Du Luoyue recover his memory, Jin Wei unexpectedly fell in love with Song Zanghai, and at this time, Song Zanghai had just chased the long-admired goddess Yaoqing, and Yaoqing was also Luo Yue's current best friend, as the middleman, Du Luoyue was in a dilemma!

And Gao Fan, who has been a friend for many years, also constantly enlightened Jin Wei not to destroy the happy life of others, Jin Wei listened, and no longer pursued Song Zanghai madly, but turned to silently like it, and decided to work with Jiang Xie, Song Zanghai, and Gao Fan to restore the memory of Du Luoyue!

The three of them secretly recovered their memories Du Luoyue, and this matter was discovered by Yaoqing. She told Zhang Chaosheng that Jiang Xian would do his best to restore Luo Yue's memory and snatch her away from him! So Zhang Chaosheng organized Yaoqing and Shi Jie to stop Jiang Xian's plan to restore Du Luoyue!

But in the end, Du Luoyue regained her memory.......

Du Luoyue, who recovered her memory, still chose Zhang Chaosheng, because she never accepted that Jiang Xian betrayed her back then, and she was P-legged Qiao Xue. Although he broke up with Qiao Xue and came to Beijing for her sake in the end, all the later remedies could not make up for the harm done to her back then!

After Du Luoyue regained her memory, Song Zanghai and Yaoqing got married, and Jin Wei chose to leave Beijing because she couldn't stand it, but unexpectedly received a marriage proposal from her friend Gao Fan for many years!
