In the second semester of her sophomore year of high school, Su Wanqing transferred to the key high school Jiangcheng No. 1 Middle School due to her parents' job transfer, and was arranged to be at the same table as Shen Mochen, the top student in the grade. At first, Shen Mochen's coldness kept Su Wanqing away, but her sunshine and sincerity, like a warm current, gradually melted the ice around him. In the boring and stressful days of preparing for the exam, the two secretly developed feelings while getting along day and night. Shen Mochen's love is a silent and deep guardian, organizing notes for her, solving troubles for her, and always following her eyes; Su Wanqing's love is a straightforward and warm approach, caring about his emotions, sharing her happiness, and knocking on the door of his heart little by little. Their ambiguous feelings quietly grew with the help of their classmates, the acquiescence of their teachers, and even the support of their parents. After the college entrance examination, the two of them were both admitted to top universities. Shen Mochen solemnly confessed his love under the stars, starting a journey of ultimate sweet love for two people from campus to wedding dress.
