"Everyone you meet on a rainy day will become a special being.
Due to her parents' job transfer, Yu Yan transferred to the unfamiliar No. 1 Middle School in City X. On the first day of school, she met the girl Yun Mo who was always collecting "rainy days" in the rain.
Yunmo's frosted glass bottle contains many strange things: a piece of candy paper wetted by rain, a half-cut piece of chalk, a yellowed sycamore leaf... Everything is labeled with a number, as if it contains a secret that no one knows.
"Collection No. 43, A pebble given by the transfer student. "
Yu Yan never thought that the stone she picked up casually would be so cherished by Yun Mo. What's more, she didn't expect that the seemingly cold top student would hold an umbrella for her on rainy days and watch fish with her on the rooftop.
It turns out that some encounters are no accident, and some rainy days are destined to be collected for a lifetime.
"Yu Yan, do you know why it is number 44? "
"Because from today on, rainy days have a new meaning. "
Intention: Growth is about learning to put regrets in a glass bottle, as well as unexpected light.
