When she was sixteen years old, Su Xiaoxin handed her umbrella to a strange girl on the train. She didn't know that girl's name was Yu Ting. She didn't know that Yu Ting would jump into the river, fish her out, and say to her, "You don't want to die, okay?" She didn't know that the moment the umbrella was handed out, she herself was being caught.
Yu Ting changed her seat and sat next to her. She put a carton of milk on her table every day and copied her notes neatly. She didn't ask why she was crying, she just said "you will say it when you want to say it". Su Xiaoxin gave her glasses and celebrated her birthday. When she was beaten by her father in the street, he stood in front of her and said, "Who do you think you are?" Then she took Yu Ting's hand and ran towards the sea - "It's getting late, let's run away together."
From the rain in the East River to the sea in Qingdao, from the unspeakable words on the note to the one o'clock in the morning hidden in the music box, they all thought they were redundant until they met each other——
"What you gave me was an umbrella." Su Xiaoxin said.
"I give you a rainy day."
"Then what did I give you?"
Yu Ting thought for a while and smiled: "What you gave me is Yu Zing."
Three years later, Yu Ting turned eighteen. Everyone was giving gifts, and Yu Ting asked Su Xiaoxin: "Where is my birthday gift?"
Su Xiaoxin said: "It's me."
There are twenty-six chapters in the book, from "Are you waiting for the rain to stop" to "The rain has stopped". She pocketed her sunny day and raised her again.
The umbrella she handed out on the train turned into a whole sunny day.
