Seven years ago, Yu Zhou and Lin Yu met in Hangzhou.
She was twenty-one and he was eighteen.
She was mixing drinks behind the bar, and he was washing glasses at the sink. Later, she sat in the back seat of his electric car, wore his old T-shirt, and on a snowy night, she put her ID card into his hand and said with a smile: "I have two, and I'll give this one to you."
Later, Lin Yu went to study abroad, while Yu Zhou stayed in Hangzhou.
They contacted each other occasionally through schoolwork, work, and nights in different cities, but neither of them said the words again, and they all tried to move forward.
Until the night of Yu Zhou's twenty-eighth birthday, Lin Yu liked her circle of friends.
At 11:47 in the evening, his call came in.
He said: "It snowed in Hangzhou that year. You said, if you are not married when you are twenty-eight, marry me."
Yu Zhou opened the curtains and saw Lin Yu standing downstairs.
In his hand he held the ID card with frayed edges.
He said:
"Yu Zhou, you are twenty-eight today."
"It's not snowing."
"But I'm here."
He took her drunken words seriously for seven years before he walked up to her.
