You Have This Day Too

By day, she is Qianai, the nation's goddess. By night, she is a ruthless assassin.

Qu Yi, the mother of the aloof CEO Lu Li, orders him to marry Qianai, no matter what it takes.

After an assassination attempt, Lu Li accidentally finds Qianai's bracelet and uses it to blackmail her into dating him as part of a deal.

Once they go public, she dominates the top three trending topics, but ends up owing so much in breach-of-contract fees that she loses everything and has no choice but to move into his home.
