It tells the story of childhood sweethearts Su Wan and Qin An, who entered the university campus hand in hand, but both encountered a suitor "sent from heaven". Sunshine senior Gu Yichen's fierce offensive and scheming senior Xia Xiaorou's every step of the scheme made their lives ups and downs. However, no matter what the outside world is like, Su Wan and Qin An always firmly trust each other and work together to resolve misunderstandings and crises time after time. On the picture scroll of youth, they used companionship to write the longest confession, and finally understood that thousands of heavens are falling, but they are no match for the words "I will always believe in you." This is a sweet journey about preference, protection and growth.
