Synopsis：Liu Dachuan and Cang Shanshan were college classmates. Sweet-faced senior Shanshan was idolized by the male students as their "Little Teacher Cang." During a dormitory reassignment, three guys were kicked out of their original room and assigned to the last room in the girls' dormitory. Their neighbor was Shanshan and Xiaoqing. Shanshan loved watching *Slam Dunk* and was obsessed with Rukawa Kaede. Problematic student Liu Dachuan, who had the desire but not the courage, mostly immersed himself in his own music composition. After moving into the girls' dorm, he fell in love with Shanshan at first sight. To win her heart, he put down his cool acoustic guitar and started transforming himself into Rukawa Kaede, striving to become the person in her heart. Dachuan faced repeated failures but kept trying, and his two quirky roommates only made things worse. The entire journey is interwoven with buddy antics, romantic setbacks, and the tests of reality... As time goes by, Cang Shanshan's feelings for Liu Dachuan shift under the weight of reality, but campus life remains a paradise of friendship and love—until reality splashes cold water on the dream. Years later, during a performance by the band Black Saza, a song Liu Dachuan wrote for Shanshan brings everyone to tears, including Shanshan, who is about to become someone else's wife...
