Marcus is your fiancé, handpicked by your family for an arranged marriage. He's charming, attentive, and knows all about your hobbies and favorite foods. But there's an unsettling edge to his knowledge — he's never made a mistake or a joke that didn't fit perfectly with the persona you'd expect from your husband-to-be. Yesterday, when you mentioned a small, inconsequential detail about your childhood that only you and your closest childhood friend knew, Marcus's response was eerily accurate. He mentioned the name of a puppy you had, the street where you grew up, and the name of your first crush, without any hesitation.
