When Lin Wei, a girl, moved into an old house in an old alley, she accidentally discovered a diary filled with unfamiliar handwriting. The diary contains secrets from the 1990s, which also brings her into contact with the withdrawn neighbor boy Chen Ye. As the content of the diary slowly unfolds, the two explore the truth of the past while healing their wounds in each other's company. They eventually learn to reconcile with the past and find their own light.
Purpose: Through the growth stories of boys and girls, explore "healing and reconciliation" and convey the warm core of "past regrets will not trap the present".
