Fallen heiress Chloe escapes her stepmother's arranged marriage by impulsively kissing Alexander, Gotham's most dangerous and mysterious tycoon. Alexander, cold and enigmatic, needs a wife to secure his company's shares, and Chloe's timing is perfect. They marry in a flash, with neither knowing the other's true background.

While Alexander is a powerful, dangerous billionaire, Chloe hides her own identity as “Viper” — a brilliant clock restoration and tech genius Alexander has been secretly hunting to save his empire. This dual secret fuels the tension: she’s both his unexpected wife and the very person he’s been pursuing.

Chloe and Alexander’s marriage is born from desperation and circumstance, not love. Chloe conceals her genius status while Alexander hides his immense wealth and influence, creating an intense atmosphere of deception and guarded motives.

Jealousy, family pressure, hidden secrets, and external enemies constantly threaten their relationship, pushing them to navigate high-stakes risks while keeping up appearances.

When Chloe’s stepmother and fake socialites push her to the brink, she drops her mask — “Viper” strikes, and the two “tigers” unite as husband and wife to take down those who crossed them.

The story follows their journey through misunderstandings, crises, and eventual emotional openness, leading to a powerful reckoning and a united front against their shared challenges.
