In Xiamen, where the sea breeze blows, Ludao University ushered in a new academic year. Gu Feng, a freshman majoring in accounting, and Wang Xue from the next class met unexpectedly due to a sudden "cat disaster" on campus. Gu Feng is handsome and responsible, while Wang Xue is gentle and kind, with an almost obsessive love for kittens. From jointly rescuing stray cats, to unexpected encounters in the library; from close cooperation in club activities, to romantic trips on Gulangyu Island, the distance between the two gradually narrowed as they got along time and time again. However, family changes, the appearance of a mysterious transfer student, and their differences in future plans make this relationship full of unknowns. When the graduation season bell rings, will they go hand in hand towards the future, or will they get separated in the vast sea of people? What kind of love story will the sea breeze of Ludao witness?
