In Haicheng, where there are many wealthy families, the Shen family and the Mu family have a deep friendship, and this friendship continues to the next generation - Shen Nian and Mu Yan.
Since childhood, Shen Nian and Mu Yan have been inseparable. In the luxurious family manor, they chased flying butterflies together; in the spacious study, they read ancient books side by side. Entering an aristocratic school where elites gathered, their stories became the talk of the town.
Mu Yan, this rich and noble young man, is the object of admiration of countless girls on campus. However, his eyes always followed Shen Nian. In class, he would hand over notes filled with problem-solving ideas to Shen Nian when he was confused; during class breaks, he would silently drive away those who disturbed Shen Nian.
Shen Nian has a lively personality, and if she occasionally gets into trouble, Mu Yan will always appear in time to clean up the mess for her and rub her head lovingly. Faced with the undercurrents within the family and the outside world's doubts about their relationship, the two worked side by side to firmly protect each other. On the stage of a wealthy family, they used their youth to compose a sweet and moving love song, performing the romance and warmth that only belongs to them.
