Tan Xiaobin is Lin Lufei's first love, the two fell in love in college, and had a lot of sweet times watching the snow and the moon. Lin Lufei remembered that Tan Xiaobin was very concerned and considerate of her at that time, because she said that the jujube cake in a certain store was delicious, so she queued up for two hours to buy it for her. also often stays up late to accompany Lin Lufei, a design professional, to make design drawings. But after the two graduated, Tan Xiaobin's mother once came to the city where they lived, and after meeting Lin Lufei, everything changed.

Mother Tan first disliked Lin Lufei, who was 160 tall, was not worthy of her son with a height of 180, and then she disliked Lin Lufei's ordinary family background and couldn't help her son. But after all, the two were very affectionate at that time, and Tan's mother couldn't directly break up the two, so she proposed that only if she was pregnant could she get a certificate, and that she could only have a wedding after giving birth to a son.

At that time, Lin Lufei worked very hard to maintain this relationship, she worked in a design company at first, and her income was acceptable, but Tan's mother thought that her job was not stable enough. In order to get Tan's mother's approval, Lin Lufei began to review the public examination after work every day.

In the first year, Lin Lufei failed to pass the written examination for the public examination, which caused Tan's mother to be even more dissatisfied. At the same time, the relationship between Lin Lufei and Tan Xiaobin also began to crack, and she found that Tan Xiaobin had never spoken for herself in front of his mother. She also found that Tan Xiaobin was on a blind date with Bai Fumei introduced by her mother behind her back, and after she found out, Tan Xiaobin had no sense of guilt, only saying that she was forced by her mother.

In the second year, Lin Lufei successfully entered the interview, but found that Tan Xiaobin also came on the day of the interview, competing for the same position with herself. And Tan Xiaobin had never revealed to her about his public entrance examination to her before.

Before the admission results came out, Tan's mother suddenly called Lin Lufei and treated her with unprecedented gentleness. Tan's mother asked Lin Lufei to take the initiative to give up this position and give the opportunity to Tan Xiaobin on the grounds that Tan Xiaobin is introverted and suitable for working in the system, while Lin Lufei is outgoing and can work hard in society.

Lin Lufei finally hardened up and did not agree to Tan's mother's request. In the end, Lin Lufei and Tan Xiaobin were not on the admission list. The disheartened Lin Lufei ended her relationship and Beipiao career at the same time.

This reunion with Tan Xiaobin, Lin Lufei didn't want to care about him, but because of the requirements of the Humanitarian and Abnormal Human Research Center, Lin Lufei had no choice but to stop his crabization.

After failing in the public examination, she broke up with Lin Lufei, and Tan's mother asked her son to go back to his hometown to continue the blind date with Bai Fumei introduced by herself.

After returning to his hometown, Tan Xiaobin found that Bai Fumei was not interested in him, everything was Tan's mother's wishful thinking. After a big quarrel with his mother, he left his hometown again, and went on a blind date while looking for a job. Only then did he realize what a pity it was to miss Lin Lufei, after all, there was no girl who could give him as wholeheartedly as Lin Lufei and did not ask for anything in return.

After listening to Tan Xiaobin's experience, Lin Lufei found that he was indeed an out-and-out coconut crab. The coconut crab is actually a false crab, which lives in the hermit crab family and feeds on hairy crabs. Of course, Lin Lufei will not be knocked out of her bones by him again, and she decided to start by helping him get rid of his parasitism on his mother.

Lin Lufei helped Tan Xiaobin change his resume, kept applying for jobs everywhere, and finally received an offer, although the salary was not high, but this was also a lot of progress, after all, Tan Xiaobin's first job was still found by Tan's mother. Tan Xiaobin's rent outside has always been paid by Tan's mother. Lin Lufei helped him find a place to live with a lower rent, so that he could pay the rent with his own salary. Lin Lufei hopes to prove to Tan's mother that Tan Xiaobin has the ability to leave her and live independently. Tan Xiaobin, who gradually built up his self-confidence, was a little moved by a female colleague, and after he told his mother about it, his mother objected, and Tan Xiaobin insisted on his opinion for the first time. Lin Lufei found that Tan Xiaobin had stopped crabbing and gradually returned to normal humans, and she had completed her mission.

And the male protagonist Feng Ruyi played by Dong Yubai is a pike crab, although the shell is extremely hard, the heart is very soft. After graduating from high school, he went out to work, crawling in society, with a strong personality, a cold and hard appearance, a straight man, incomprehensible feelings, but extremely kind and gentle in his heart, and after being with Lin Lufei, he discovered the potential of the wolf dog under the appearance of the wolfdog.

One day, Lin Lufei encountered a man on the street harassing a woman, and Lin Lufei was about to step forward to stop her, but someone had already made a move before her. The rescued girl thanked the righteous and brave people, but the righteous and brave people walked away very coldly. Lin Lufei suddenly recognized that the righteous and brave man was his high school classmate Feng Ruyi.

Lin Lufei and Feng Ruyi have been high school classmates for more than a year, and the two have hardly spoken. In fact, the two were still a little unhappy, in the second year of high school, Lin Lufei accidentally found that Feng Ruyi always seemed to be secretly following her, which made her very unhappy, just as she was about to protest to Feng Ruyi head-on, but learned that Feng Ruyi dropped out of school because of a fight with someone on the way out of school. So later, the classmates in the class had no contact with Feng Ruyi, and he did not attend the class reunion.

Lin Lufei stepped forward to greet Feng Ruyi, but received a cold response from Feng Ruyi's extremely impoliteness. Before Lin Lufei could get angry, he found that Feng Ruyi was also crabbing. She remembered her mission and decided to help Feng Ruyi.

Lin Lufei wanted to ask Feng Ruyi out to talk about Feng Ruyi, but Feng Ruyi ignored her at all. Lin Lufei could only ask He Yin about Feng Ruyi's situation. Feng Ruyi has been a left-behind child since he was a child, his parents are working outside, he and his grandmother depend on each other, and the family's economic conditions are not good. When he was in junior high school, Feng Ruyi's parents both died in an accident. But Feng Ruyi was very strong and insisted on being admitted to the best high school in the city. When Feng Ruyi was in school, he always gave the impression of abiding by rules and disciplines, and being excellent in character and learning. The teacher and classmates didn't know why he suddenly got into a fight, and it was he who took the initiative to beat the other party very lightly. According to this situation, Feng Ruyi should bear legal responsibility, but the other party did not pursue him. Even the school did not expel him, but only persuaded him to quit. Feng Ruyi later transferred to another slightly worse high school to continue his studies, and in his third year of high school, his grandmother suddenly fell seriously ill, Feng Ruyi gave up the college entrance examination and came out to work to earn money to treat his grandmother's illness. It's a pity that in the end, my grandmother died.

Lin Lufei felt that there were two major doubts in Feng Ruyi's past experience, the first was why he, who had always obeyed the rules, suddenly got into a fight with someone, and the second was why the person he beat did not hold him accountable, and it was said that Feng Ruyi's family background should not have the money to compensate the other party. Lin Lufei thought that as long as these two doubts were clarified, Feng Ruyi could be prevented from turning into a crab, but Feng Ruyi's attitude towards her was as cold as ever, and he was completely unwilling to communicate with her.
