Lu Yanting is six years old and hates rainy weekends the most.
But on this rainy day, a strange man came to the house - dressed in black, wearing a mask and sunglasses, he came in through the window, and asked him to call him "Grandpa".
This man looks like he is only in his early twenties, but he can hold his father down on the dining table with one hand; the tattoo on his back can come to life; he has lived for so long that time has forgotten to inscribe him.
"Grandpa Zhang" told Yan Ting a long story in the living room on a rainy day.
"It's a pity that I don't like telling stories." Zhang Yuehai said.
"You look like the kind of person who likes to share at first glance, but in fact you don't like to share that much. You must have experienced a lot." Said the six-year-old child.
Children's words are unbridled, but they reveal the deepest thoughts of the immortal.
This is a story about protection - how a person who cannot grow old learns to stay in the mortal world in a hundred years; it is also a story about waiting - how a six-year-old child uses the clearest eyes to see through the loneliness that adults cannot express.
Old rain brings new knowledge, old friends return.
Turning the first page is an encounter that spans a century.
