Sprint genius Lin Ye fell to rock bottom due to groundless doping charges, but when his career was at a critical stage, he bound to the "Sports Glory System". In exchange for injury repair fluid, he entered into a one-year flash marriage deal with Su Wanqing, the daughter of technology giant. One is a down-and-out athlete who endures humiliation, and the other is a clever young lady. They are supposed to have a contractual marriage without interfering with each other, but they are forced to intersect due to system tasks: from "letting her cook breakfast" to "breaking the track record", Lin Ye returns to the top with the secret help of system rewards and Su Wanqing. However, the old love returns with a conspiracy, and the coach's sinister plan is gradually revealed, which also involves the old case of Su Wanqing's mother's car accident. When the competition field becomes a battlefield of revenge and proof, Lin Ye gallops on the 100-meter track, not only to regain his own glory, but also to confess to the girl who was sincere in the transaction - this marriage that began with the exchange of interests will eventually reach the destination in both directions with sweat and love.
