When a 28-year-old soul lives in an 18-year-old body, Qin Moran's biggest wish is to make up for the regrets of youth, especially to find Shen Lin who almost gave up painting because of her unintentional words back then. In this life, she began to take the initiative to approach this taciturn boy, using various lame excuses to ask him for painting lessons, and forcefully taking him to join the club to avoid unnecessary trouble for him. Shen Lin was initially wary of this overly enthusiastic "weird classmate", but was gradually melted by the sincerity and concern in her eyes that transcended his age. He taught her painting techniques, and she taught him how to believe in his talent. Under Qin Moran's "future perspective", she became Shen Lin's most loyal guardian and guide. When she finally helped him regain his self-confidence, Shen Lin discovered the secret that only belonged to the future in her sketchbook - he drew her old appearance and wrote next to it: "No matter which life I live in, I will find you."
