It tells the sweet story of college love between Dong Maomao and Li Yu with the most adorable height difference. Dong Maomao is a junior female student with a small stature and a simple mind. She is less than 160 and wants to grow taller, but God does not hear her request, and she has a baby face. As a result, she is regarded as a junior high school student every time in college. It's strange to say that her college counselor just liked her, and after her business administration major was divided into classes, he resolutely made her the monitor. Classmate Maomao has a long way to go. But our Maomao's boyfriend Li Yu is a typical Cancer, with a gentle and sensitive personality. Not only does he have a height of 182cm that makes Maomao envious, but he is also well-developed morally, intellectually, physically and aesthetically. If distance is the biggest obstacle to love, then the height-crossing love between Maomao and Liyu is undoubtedly a failure. Sometimes fate is just right. You start from the starting point and I wait for you at the end. It seems that everything is destined. The meeting between them was like a wonderful journey. Two people on different lines met on the same train. Liyu's coffee accidentally spilled on Maomao's white dress. Looking at such a cute and innocent Maomao, Liyu fell in love with her at first sight. He thought that since he met her, he should not run away. Such a cute girl will definitely add a lot of fun to his life. So Li Yu began a short but sweet journey of chasing the cat.
