"You are the only definite answer I have calculated over billions of light years."
On the day when ten-year-old Lin Xiaoman moved into Wutong Lane, he saw the cold eyes of a boy riding a bicycle through the car window. Chi Yan, thirteen years old, a genius boy and the legend of Xingchen Middle School, climbed over the wall that summer evening and rescued an injured stray cat for her.
From math tutoring to the secret base under the stars, from the back seat of a bicycle to the aerospace exhibition hall, she is the only variable in his formula, and he is the eternal theme on her drawing paper. When Lin Xiaoman's sketchbook quietly filled up Chi Yan's profile, when the abbreviation "LSM" began to appear on Chi Yan's aerospace model, the entire youth was brewing unspoken confessions amidst the rustling of sycamore leaves.
However, growth is never gentle - he is forced to face the choice between his father's control and his dream of aerospace. She struggles in the whirlpool of artistic pursuit and self-doubt. The opportunity to be an exchange student in France, a sudden family change, the urgent call of the aerospace project... When fate pushes them to the opposite ends of the earth, can those unfinished words still cross the galaxy?
"I would rather miss a thousand launch windows than miss a life orbit with you.
From youth to reunion after a long absence, from Wutong Lane to the launch base, this is a growth story about how two stars find each other's orbit. When Chi Yan stands in the satellite launch command center, and when Lin Xiaoman's paintings hang in international art exhibitions, they will finally understand that the greatest aerospace project is to calculate the trajectory of the encounter of two hearts; the most moving work of art is to record the growth rings of a period of common growth.
