Cherry Blossom and Abo are ready to build a new house, but they don't have enough money. Uncle and aunt decided to rent out Ah Yin's room. So the sign of "there is a house for rent" hung at the door of the house. On that day, the whole family in Yin's house was talking about renting a house, and it happened that A Yin came back. As soon as A Yin entered the door and saw that his room had been rented out, he flew into a rage, didn't say a word, turned around and went to the station. The cherry blossoms hastened to catch up, but A Yin had run away. An angry A Yin came to a housing rental company to find a cheaper house to live in. The rental company said there was, so he drove A Yin to the "rented room in Yinwu". When he returned to his own house, Ah Yin was crying and laughing, and the guy from the rent company said to A Yin, "Sir, the agreed service fee is 6000 yuan." Ah Yin was even more angry and quarreled with him. As a result, Abo paid for it. That night, A Yin argued with his aunt and uncle about his room being rented out for a long time, and said a lot of mean things about Cherry Blossom and Ah Bo's desire to build a house, and finally made Sakura cry angrily. After this, A Yin went on a trip to the north again. They met Arden in Kanaka, and they met the song from Tokyo at the hotel.
