The story begins on a misty morning in a water town in the south of the Yangtze River. Lin Weiyang, with her parents' tender and reluctant farewell, boarded the high-speed train to Star City, the city where the university is located. In the carriage, she looked out the window at the familiar scenery receding rapidly, and her longing for the future and the faint sadness of leaving home were intertwined in her heart.
Lin Weiyang arrived in the bustling Star City and moved into the dormitory under the enthusiastic guidance of her seniors. She met her lively and outgoing roommate Su Xiao. Su Xiao was like a "little sun", quickly dispelling Lin Weiyang's strangeness and uneasiness. The two tidied up the dormitory and visited the campus together, and initially established a warm friendship. Through conversations, they heard a few words about the name "Lu Beichen" from another person for the first time.
