Signing a contract for a fake marriage to pool together a down payment for a new home, she originally only wanted to steadily earn a sum of remuneration, but the Civil Affairs Bureau mistakenly made her and Pei Corporation CEO Pei Heng wrongly collect their marriage certificate. The two agreed that when one year expires they will divorce and be even with no debts owed, but their interactions gradually warm up. She single-handedly shoulders all the frustrating matters brought by her harsh relatives, love-brained younger sister, and irresponsible brother-in-law, while Pei Heng always silently protects her safety and steps forward again and again to clear troubles for her. The originally cold transaction contract deteriorates in day-after-day companionship, Pei takes the initiative to tear up the compensation agreement, sheds his wealthy family disguise to confess his true feelings, and this accidental blunder of a marriage ultimately achieves a sincere romance of two-way rushing towards each other.
