Lin Xingyao and Lu Zhiyan's fates became entwined on a summer night in 2000, when a mix-up in the maternity ward led a nurse to switch their babies, binding their two families together from then on.
He is a cool-headed, rational engineering genius whose life follows the precision of code: an Olympiad gold medal, a top university, and founding Xingtu Technology right after graduation. She is a gentle, sensitive art student whose world flows with colors and lines, and whose dream is to warm people's hearts with her paintings.
In everyone's eyes, they are childhood sweethearts straight out of a textbook: their parents meet for dinner every week, they are inseparable from kindergarten through high school, he shields her from every storm, and she is the only variable he allows into his private world.
Only Lu Zhiyan knows this is no coincidence.
From sharing the same strawberry cake at age three to holding hands for the first time beneath the stars at eighteen, from using software he developed himself to enhance her paintings in college to her quietly taking commissions and supporting half the household during the hard early days of his business, every step is part of the secret algorithm he calls “Project Xingyao.”
When Shen Yan, a sunny art student, appears and openly pursues Lin Xingyao, Lu Zhiyan stays up all night writing a hundred thousand lines of code. At a product launch, he declares in front of all the media, “This product is named after the girl I've had a crush on for twenty years.”
Only then does Lin Xingyao realize that what she thought was “letting things happen naturally” was a sweet trap he had carefully designed with his rational mind. From the identity bracelets they wore on the day they were born to the QR code on their wedding invitations, he had written the course of their lives together long ago.
