Twenty-eight-year-old Wen Ran has a personality like a lit stick, crackling wherever he goes. She is a tour guide in Lin'an City. She has a loud voice, loud laughter, and low tears. Her favorite things are eating hot pot (although she can't eat medium spicy) and nosy.
Seventeen-year-old Jiang Wanwan works as a summer job at a hot pot restaurant. She is 1.82 Meters tall but always stoops, with bangs covering half of her eyes. She doesn't like to talk or laugh. Apart from her mother and sister, the only woman among her WeChat friends is a strange sister she met at a hot pot restaurant.
She called him "Wanwan", said that he had beautiful eyes, that he was cute, that there was an old child living in him, and that he should wear more bright-colored clothes. He called her "Sister Ran", saved every emoticon she sent, remembered every word she said, and secretly straightened his back a centimeter for her.
A carefree sister and a taciturn young man. The eleven-year gap was like a transparent wall. They stood on both sides of the wall and could see each other, but they didn't dare to reach out.
But the heartbeat thing never waits until someone is ready.
Later she said to him: "I have seen you before." Before you knew me, before the summer when you were seventeen, I had seen you.
This is a story about encounter, companionship, miss and reunion. About how two people who are eleven years apart leave the deepest mark on each other's lives. About how a teenager goes from feeling inferior to being confident, and how a woman goes from taking care of others to learning to be taken care of. And - about how she traveled through time and waited for him to grow up over the long years.
