Su Xiaotang, a energetic girl from the Chinese Department, got lost on her first day of school. She mistakenly recognized Lu Xingyan, the top student in the Computer Department, as a "senior" and spilled milk tea on his white T-shirt. This unlucky incident became the starting point of their fate. From then on, from sharing notes in general classes, transferring sweet and sour pork ribs in the canteen, to working together in clubs to stay up late to change plans, and using ice packs to protect injuries during sports games, the two gradually fell in love in their trivial daily life.
With the help of gossip from the best friends group and the encouragement from the brothers group, the misunderstanding was gently resolved, the rooftop talk confirmed the feelings, and the confession at the starry sky camping made the two sides rush to the ground. The cross-city surprises during the long-distance summer vacation, the mutual support for postgraduate entrance examinations and employment, and the playground proposal during the graduation season. They grew up from young freshmen to side by side young people, and turned the heartbeat on campus into a long-lasting sweetness.
There are no vicious supporting characters in the whole text, and it is connected with details such as handbooks, basketball, and "The Little Prince" to record the growth and love from freshman year to graduation, and finally extends to the daily life after marriage in renting a house in Beijing, using "daily sweetness + growing up together" to interpret the purest appearance of campus love.
