A cemetery on a stormy night becomes the starting point of a contract. Su Wan clutches a forged medical record and takes her younger sister's place as the bride of Fu Chenyen, the head of the Fu family, who is rumored to bring death to his wives. As their marriage certificate is stamped in front of a tombstone, she fails to notice the undercurrents in his eyes: the red mole on her neck matches the memory of the little girl who once bandaged his wound in an alley.
Everyone knows Fu Chenyen as a cold-blooded tyrant, but no one sees him personally adjusting the folds of her dress as she tries on a gown, or crushing her stepmother's arrogance with a checkbook when she is harassed. Nor do they see the almost reverent tenderness in his eyes when she picks up a paintbrush. This “fake heiress,” trampled into the dirt, can conjure a starry brilliance with a flick of her fingers, enough to set the jewelry world ablaze. Beneath the secret identity she hides as “Night” lies the business empire her father left her, as well as the mutual salvation neither of them voiced five years ago.
From an arranged marriage to being cherished beyond measure, the deal they made in a cemetery gradually reveals its heart of sweetness. In the dead of night, Fu Chenyen will wrap her in his suit, brush his Adam's apple against her earlobe, and murmur with a laugh, “You used your bracelet to stop my bleeding back then. Now it's my turn to repay you with the rest of my life.” When Su Wan sees the old keepsakes he treasures in his safe, she suddenly understands that this marriage, which seemed like a scheme, had planted the seeds of his devotion long ago.
A marriage that began with mutual benefit ultimately becomes the sweet refuge through which they save each other. The satisfaction of face-slapping and taking down scoundrels, the tenderness hidden in the folds of a suit, and a love that finds its way to each other across five years weave together a sweet romance in the world of the wealthy. Think this is a marriage of convenience? No, it's a long-planned devotion. From the moment they met, their whole lives had already been written in sweetness.
