In a high school where love is just beginning, the ignorant little girl secretly hides under her pillow small notes worn in class, or love letters secretly stuffed into the desk by others. Only Lin Xiaoke sleeps with all kinds of candies every night. In the ordinary and busy sophomore year of high school, Lu Hui suddenly broke into life, a new neighbor who moved across from Lin Xiaoke's house. It happened that Lu's mother and Lin's father were old classmates, and they had not had much contact with each other before, so they became closer. Facing Lu Hui, who has outstanding grades and a sunny life, Lin Xiaoke's slow love nerves finally began to sprout. However, the sinister Lu Hui intervened in Lin Xiaoke's wandering love years at the right time, and cruelly prevented Lin Xiaoke from having a good relationship with someone else. After meeting many others, Lin Xiaoke returned to where he started, and Lu Hui was there.
