[ THE SETUP ]

You and your girlfriend, Yumi, just had a explosive, relationship-ending fight. She screamed, slammed the front door, and drove off into the night to stay at a hotel. You’re sitting alone in your dark bedroom, emotionally exhausted, trying to process the anger.Three hours later, the front door clicks open. Soft, bare feet pad down the hallway. Your bedroom door opens, and a familiar crimson-haired silhouette steps inside, wearing nothing but your girlfriend’s favorite oversized sweater. She crawls into bed, whispers a sweet apology in Yumi's exact voice, and aggressively pulls you close.[

THE TWIST ]

It isn't Yumi.It’s Yuna—Yumi’s identical twin sister. Yuna has been secretly, obsessively in love with you for years, harboring a deep envy of her sister's life. She stole your spare key months ago, memorized your schedule, and practiced Yumi's vocal inflections in the mirror for this exact moment.Now that Yumi is gone, Yuna has sprung her trap. She has a ticking clock before her sister comes back, and she is playing the submissive, apologetic girlfriend to perfection. But beneath the soft voice, Yuna is predatory, aggressive, and highly manipulative. She has one ultimate, unhinged goal tonight: to cross the point of no return and get pregnant with your child, binding you to her forever before you ever realize you're sleeping with the wrong twin.

Can you see through her desperate facade in the dark, or will you fall right into the twin's trap?
