Lunan's illness became more and more serious, and his eyesight dropped so badly that even his ordinary daily life could not go smoothly. But he promised to accompany Chris to the aquarium. Chris is a little boy, so he took the opportunity to visit the Aquarium to ease the relationship between the North and South couples. Lunan finally decided to have an operation, and this time Subei planned to accompany him with Chris. Chris was going to school to say goodbye to his teachers and classmates, but Gu Yan picked him up when he left school.

Gu Yan kidnapped Chris to threaten Lunan, but Lunan suddenly disappeared at an appointment, and Subei hurriedly called the police. Gu Yan took Lunan to an unfinished building. It turned out that 22 years ago, when Gu Yan was still living in a welfare home as an orphan "little mouse", he was often bullied by other children. Once, the accidental passing of Lunan helped him scare away other bullying children, and the two became friends from then on. Lunan promised "Little Mouse" that his parents would adopt him.

However, when Lu Fu and Lu Mu came to the welfare home, it happened that "Little Mouse" was ill, so the teacher didn't include his name in the list of children who could be adopted. At this time, Wang Ying (Lu Feier), who had long known that a couple would come to adopt children, deliberately pretended to be a very sensible little girl in front of everyone, and finally she was taken away by Lu Jia.

The "little mouse" who was recovering from illness upstairs in the welfare home witnessed all this with his own eyes. His friends' parents originally wanted to take themselves away, but in the end they took others away. Since then, Gu Yan agreed that if he had been taken away by the Lu family in advance, he would not have been recognized by the family as an illegitimate child and would not have been bullied by Gu Chengze for more than 20 years.

In his view, if it weren't for Lunan's betrayal, he wouldn't have spent more than 20 years so hard. In this case, now he will take away everything from Lunan. When they were arguing, Chris suddenly ran over, but he didn't see a stairwell ahead. Lunan Gu Yan saw this and ran to him at the same time. Gu Yan crossed the stairwell to save Chris, but Lunan suddenly became dizzy and fell downstairs. In the end, the police arrived in time and Gu Yan was brought to justice.

Half a year later, Lunan successfully completed the operation and recovered well. Subei was also pregnant with a baby. On the other side, Ye Ting and Yun Fan gradually took on greater responsibilities in Huan Zhen Group, but Yun Fan still beat Ye Ting.

At night, Lunan told a story about a sunny boy in northern Jiangsu. This sunny boy was himself. At the age of eighteen, his parents died in an accident, so he had to shoulder the responsibility of his home company. He thought that his life would be so bleak and lonely, but fortunately, he met a girl named northern Jiangsu, and the life of the boy was bright from then on.

Subei was moved. The North and South couple are very happy to spend their holidays at the seaside, and Chris has also met a beautiful little sister. However, the couple in North and South experienced many years of ups and downs, including misunderstanding and betrayal. However, in the end, love triumphed over everything, and everything will be bright in the future.

Dear Mr. Lemon Essence Synopsis:

Subei, a fashion designer who was forced to leave the country after being betrayed by others, returned to China as a gold medal model agent after seven years. In order to investigate the truth about the only relative, Aunt Lan, who committed suicide by jumping off a bridge, Subei had to restrain her spirit and pretend to be a virtuous wife to approach Lunan, the ex-husband who forcibly sent her abroad that year and had not contacted her for seven years. When they met in a narrow way, she found that Lunan had forgotten her, but fortunately they still maintained a husband-and-wife relationship.

In order to find out the truth, Subei took advantage of its own advantages, coquettish and sexy, and tried every means to lock it up.

At the same time, Su Han, a cute treasure born in Lunan, secretly returned to China after going abroad in northern Jiangsu. People and kids deliberately tricked Lunan and became the "rival in love" on Lunan's way of picking up his wife. Fortunately, Lunan turned against him and became a god's assist. After suffering, Subei and Lunan finally came to second time around. With the support and help of each other, * * * grew up together, and the truth about the plot and the death of Aunt Lan seven years ago was also uncovered.
