Lin Xiran came from a single-parent family. After her mother, Lin Nianan, divorced Su Hao after giving birth to her, she regarded Lin Xiran as a burden and never cared about her.
Lin Xiran suffers from depression, but she behaves like an optimistic and generous little fairy in front of outsiders.
She fell into an abyss. Later, Jiang Lin appeared and he pulled her out of the abyss.
From then on, there were stars and the moon in Lin Xiran's dark world, and Jiang Lin was her night light.
The night light will eventually disappear, and those who break the promise will never lose their love.
Purpose: Feelings after seeing patients with depression, hoping to be relieved
