"Your hands are so cold."
Seventeen-year-old Shen Zhirou handed him a cup of hot milk tea, which was the warmest thing he had ever heard.
Later, he chased her through three cities and saved more than 100 tickets. He wrote on the back of each ticket: "Today she cried", "Today she said she missed home", "Today she pushed me out the door and said, 'Let's go'".
He doesn't even leave.
Because she was the only person he didn't want to miss after he opened the door on a rainy day when he was seventeen years old.
This is a story about a girl with depression and a boy who "only loves her in stupid ways". They loved stupidly, separated, cried, and almost gave up. But in the end they learned - loving someone is not about pulling the other person out of the abyss, but squatting on the edge of the abyss and saying "I am here".
People who push through the door on a rainy day want to get out of the rain.
But some people hide in and never want to go out.
