A blurry videotape of a short video of a baby. A woman's voice complimenting him on his cuteness comes from a voice-over, and the video ends, followed by Matthew Green, whose Korean name is Kang Sung-min - saying to the camera that he wants to find his biological mother. He was adopted by an American family as a child, but he did not have a hukou. He grew up in the United States, but was not an American citizen, and was eventually deported back to China. In South Korea, he didn't speak Korean, was helpless, and ended up in his bachelor apartment, following a report from anchor Kang Eun-jung, when he suffered a heart attack and passed out as he struggled to get his medicine.
In the morning, Cao Shangjiu was wiping the car with Shushu outside. He tried side by side to test whether Shulu knew that Ke Lu was not Han Jingyou's biological child, but Shushu had no idea about it. Sure enough, after chatting for a while, the tree was angered by Cao Shangjiu again. As soon as Cao Shangjiu returned home, he received a new commission, so he and Ke Lu packed up and set off. When they came to the commission, Ms. Sun Youlin informed them about Matthew Green's situation.
The uncle and nephew began to organize. They found a lot of magazines about Jiang Eunjing's anchor in his room, and a photo of a girl holding her childhood Matthew Green. Kelu found a pet sign in the bathroom that said Yazhi, but the puppy disappeared. After they came out, Sun Youlin brought them drinks, but Lu asked her if she knew where Yazhi was? Sun Youlin replied that Yazhi is now in the hospital. Cao Shangjiu wondered, Matthew Green has been in Korea for four years. Hasn't she tried to find her relatives? Sun Youlin replied that of course he tried, but his mother was reluctant to come to see him. She also said that Matthew Green was abandoned because his adoptive parents found out that he had a heart problem after he arrived in the United States, so he has never been granted U.S. citizenship. At this time, Kelu took the relic box and wanted to give it to Matthew Green's mother. But Sun Youlin told Kelu that because his mother refused to meet, the adoption center could not provide her information, so there was nothing she could do. After returning home, Kelu put together the scraps of paper in Matthew Green's room one by one into a complete book, the author is Jiang Enjing. By comparison, the girl in the childhood photo of Matthew Green and a girl is Jiang Enjing. So Kelu decided to find Jiang Enjing and give her the relic. They came to her work unit and saw her from a distance, but were stopped by staff. In desperation, they had to drive with Jiang Enjing all the way to her door.
After getting out of bed, they stopped Jiang Enjing. After knowing their purpose, Jiang Enjing took them to a quiet shop. Ke Lu and Cao Shangjiu told her about Jiang Chengmin's experience and death. After Jiang Enjing heard it, she burst into tears. She told them that she was not Jiang Chengmin's biological mother. She was only 16 years old at the time, and their family was responsible for taking care of the child before he was adopted overseas. Jiang Enjing liked Jiang Chengmin very much, and was particularly impressed by him. She sighed with regret that if he came to find her, she would definitely remember him. Ke Lu told her that Jiang Chengmin actually went to the reader meeting to find her, but because Jiang Enjing did not want to see him, he did not say that he was Jiang Chengmin. After returning, Matthew Green hysterically tore the book to shreds, page by page. Jiang Enjing thanked Ke Lu and the others for reminding themselves of the child Jiang Chengmin, Ke Lu and Cao Shangjiu also apologized to Jiang Enjing for the previous misunderstanding. The two then drove to the veterinary hospital. There Sun Youlin adopted Yazhi. Seeing that Sun Youlin and Yazhi were so close, Cao Shangjiu unconsciously touched his hot ears. On the way back, they saw Jiang Eunjing reporting on Matthew Green on the roadside big screen, asking the government to take care of the children who were adopted abroad, and apologized to Matthew Green on behalf of South Korea. The car drove away slowly, and Ke Lu suddenly sighed and said that he might have become Matthew, but he met Han Jingyou's father, so he became Han Kelu. After returning home, Cao Shangjiu received a text message from the woman telling him that the game would be played tomorrow.
Early the next morning, Ke Lu just woke up and saw Cao Shangjiu preparing breakfast for himself, so Ke Lu thought that Cao Shangjiu was suffering from a terminal illness. After a while, the tree came, and Cao Shangjiu told the tree that Ke Lu asked her, and then turned and left gracefully. The tree quickly told Kelu that something had happened to Cao Shangjiu. Ke Lu told her that Cao Shangjiu cleaned the house and made breakfast, but he did not suffer from a terminal illness. He repeated to the trees what Cao Shangjiu said when he called the woman last night. Tree was very worried, and she found a document about Boxer's Encephalopathy Syndrome in Cao Shangjiu's tent. After Ke Lu explained the disease to her, the tree began to worry that Cao Shangjiu might die on the field. On the other side of the underground boxing arena, Cao Shangjiu slowly entered the arena. This time his opponent was a tall Russian.
