The vain Xue Fei puts on airs as a wealthy tycoon at a class reunion. After being exposed by his hard-working wife Yang Fan, he accidentally travels back in time five years to college. Relying on foreknowledge, he writes songs that skyrocket to fame, builds a company, and flamboyantly chases the campus belle Ai Feier, all while consistently ignoring Yang Fan who silently manages finances and handles logistics behind the scenes. After acquiring ten billion in wealth, Yang Fan resigns in disappointment. Through a system, Xue Fei sees how Yang Fan spent years searching for him in the original timeline, waking up to the truth. He gives away his entire fortune to win back his wife. Yang Fan is heavily injured in a car accident, and Xue Fei transfuses his own life blood until he nearly fades away into nothingness. Finally, time reverses, and Xue Fei returns with bodyguards to Yang Fan's barbecue stand, where the two untangle all regrets and spend the rest of their lives together, proving that sincerity is far more precious than wealth.
