Kiyosumi Sena, a brilliant otome game developer, loses everything in an instant—her beloved job, her secret office romance—after being framed by a junior colleague. Just when despair threatens to consume her, she has a fateful encounter with Kagura Ryo, a rigid and socially awkward heir. Their first meeting? Nothing short of a disaster.
Then, out of the blue, Ryo makes an unexpected proposal: To revive the struggling romance simulation game Secret Fake Love Marriage, he suggests they enter a real contract marriage themselves. The deal is simple: a marriage with no love, just an expiration date.
But as they re-enact romantic scenarios from the game in real life, Sena finds her heart racing in ways she never expected. Could the love that started as a sham ignite something real? What will become of their contract marriage?
