Ni Nan was moved at first sight when she saw Shen Xian.
That day Shen Xian asked her, "Children, do you like sweets?"
Ni Nan nodded.
Later, Shen Xian brought some different candies to her children every day.
One day Ni Nan saw him smoking and accidentally choked him.
"Can't you just stop smoking?"
Shen Xian smiled casually, "I can't quit, kid."
But then Ni Nan never saw Shen Xian smoking again.
Later, Ni Nan never saw Shen Xian again.
Later, someone asked Ni Nan if he had any regrets.
Ni Nan thought for a long time and said, "I have let it go."
Purpose: to make up for regrets
