Eighteen-year-old Jiang Liang donated his corneas to his sister, and his good times were lost. He stayed in the house all day until he met seventeen-year-old Bai Huan.
She is the wind, coming uninvited and leaving by itself. It became a beam of light in Jiang Liang's life.
They lived in an alley. Jiang's parents didn't care about him, so Bai Huan stayed with him all day long.
As she stayed with her, Jiang Liang developed feelings for her, but he couldn't see it and was not worthy of her.
Maybe eighteen-year-old Jiang Liang had a secret love for a girl, but she came like the wind uninvited. Someone donated an eye mask to twenty-year-old Jiang Liang, and when he wanted her to come, she was lost.
Concept: When the wind comes, it comes uninvited
