Under the old vines of Ivy Middle School, there are secrets and bonds among young girls. Transfer student Shen Yu can see light, monitor Xia Xingmian can hear the whispers of old things, sports committee member Lu Zhiye will get hot when touching metal, and literary club president Wen Tang can see pictures when reading words. When "abnormalities" occur one after another on campus, they gather together because of these wonderful "differences". While guarding the ivy and exploring the relationship between themselves and the world, they compose a movement of youth and growth, and slowly uncover the past about the "boundary monument" and the "monument keeper".
Purpose: Young people learn to accept themselves and protect each other through ignorance and exploration, and find the direction of growth and the fetters of life in the intertwined youth of the ordinary and the extraordinary.
