Su Zhao goes to a blind date in place of her best friend, enters the wrong private room, and somehow signs a marriage contract with Lu Riheng, the city's most powerful man. They get their marriage certificates just an hour later.
Burdened by the medical expenses for her seriously ill adoptive mother, she decides they'll only share a household, not fall in love. They'll live together in separate rooms, split expenses evenly, and she'll never touch a cent of his money.
Little does she know that her new husband, who calls himself an ordinary project director in public, is secretly the president of the Lu Group, commanding a business empire worth hundreds of billions. He disguises his identity and quietly plays along with her.
Afraid of hurting her pride, he discreetly gives her high-paying freelance design work.
When he sees her staying up late to finish designs, he quietly drapes a light blanket over her late at night.
When everyone at work ostracizes her and maliciously spreads rumors that she got ahead through connections, he publicly stands up for her and crushes every slanderous accusation.
Through sheer design talent, Su Zhao turns the tables against all odds, tears the rumors to shreds, and becomes a radiant beacon.
Only later does she learn that this unexpected, mistaken marriage was never a coincidence. It was his long-planned journey to be with her.
In a world full of dim, ordinary people, only Su Zhao shines like the sun and moon, illuminating the lonely years of his life.
