Mr. Lin Is My Little Puppy

Yu Miaomiao has a neighbor brother who is 3 years younger than herself. The two grew up together and have a very good relationship. Scene 1: Yu Miaomiao is 6 years old and Lin Zijin is 3 years old. When Lin Zijin learned that he could not be in the same school as his sister, he sat on the ground and started throwing a tantrum. Yu Miaomiao, who was supposed to be in first grade, went to preschool for another year. Scene 2: Yu Miaomiao is 18 years old and Lin Zijin is 15 years old. On the day when Yu Miaomiao finished her college entrance examination, Lin Zijin saw a boy confessing his love to her. He rushed forward and said, "My sister doesn't like you, so you should find someone else." Then he pulled Yu Miaomiao away. Scene three, on the eve of Yu Miaomiao going to college. Yu Miaomiao and Lin Zijin were walking on the street, buying items needed for the university. "I feel like I've been chasing you my whole life, and I'm so afraid that one day you will be snatched away by someone else." "Am I not always by your side?" "I don't want to hold it in anymore, and I don't want to get along with you as a younger brother all the time. Yu Miaomiao, I like you, not like a younger brother likes a sister, but like a boy likes a girl. Can we be together?" Scene 4: Ever since the two of them got together, Yu Miaomiao felt that Lin Zijin had become more and more attached to her and acted more coquettishly.
