The little girl named Yue Daoyong is in middle school. Like every graduating student, she is also faced with future choices. But she is not a girl who is addicted to her lessons. She likes to read more extracurricular books and write down her feelings. One day, Yong sent a box lunch to his father who was a librarian. On the way, he met a fat cat and took the tram like a human. Curious, she traced all the way back to the source, so she found an ancient and exquisite toy store-"Earth House" on the hillside. The cat doll baron on the table in the shop shone with magical aura, which fascinated her deeply. On the way home, a boy brought back her forgotten lunch. The fat cat that disappeared before is sitting in the back seat of the boy's bike with a smile on his face. So a magical fairy tale began between the boy and Yong.

At this time, other old musicians, Moon Island King and Moon Island Sunseeker, also came back, so they played their own instruments in the "earth house". The warm little concert ended with happy applause. After being introduced, Yong got to know the boy who studied violin. Shengsi confided her dream of going to the ancient piano school in Italy. Inspired by the love story of Baron Cat in the toy store, Yong also decided to write a story about Baron Cat-the story that two people who love each other can't be together because of various misunderstandings.

Both Yonghe Shengsi are facing the crossroads of graduation choice, but they have firmly chosen their own yearning path. Under the pressure of study and examination, Yong finally finished the novel and showed it to grandpa in the toy store. Grandpa was deeply moved and told the true story of Baron Cat. It turns out that the story of Baron Cat coincides with the story written by Yong. All these wonderful experiences intoxicated Yong. Shengsi finally got the understanding of her parents in China, and finally she could go to Italy to learn piano-making skills. Finally, at that sunrise, under the clear sky, before leaving, the sage bravely confessed to Wei, and Wei happily agreed. They embraced-the saint shouted, "Marry me!" "
