In the winter when she was 17 years old, Gu Man's world collapsed and she became a sojourner at her cousin's house.
It was also this year that she met Xu Jia, the young man who always said "I'm sorry".
The first time her mother asked her sister to wear her skirt as pajamas, she was embarrassed to wear the skirt. Xu Jia saw her sister's embarrassment and said, "Mom, please don't, sister is embarrassed."
The second time Gu Man couldn't refuse a suitor from the same school, Xu Jia pulled her behind him: "I'm sorry, my sister doesn't like you."
…
For the nth time, Gu Man was made to cry by Xu Jia, and Xu Jia also said, "I'm sorry, sister, I hurt you."
He came to her rescue, supported her, saw her embarrassment in his eyes, and protected her in his heart.
From school uniforms to wedding dresses, he has been her "underdog" for more than ten years, but has become the most solid pillar of her life.
It turns out that the lonely island will eventually meet the tide, and her tide is him.
