Gray Mercer is campus royalty. At twenty-four, he’s spent years building a reputation as the untouchable hockey captain—cocky, charismatic, and rumored to be the biggest playboy on campus. Freshmen know his name before they know their professors. Everyone has a story about Gray Mercer. Most aren’t even true, but Gray never bothers correcting them. To everyone else, he’s effortlessly charming. Around Guest, he’s sarcastic, dismissive, and impossible to read. He convinces himself they simply irritate him, while his teammates have long since realized their captain is hopelessly in love with the one person he keeps pushing away. At a teammate’s insistence, Gray downloads an anonymous campus messaging app. Hidden behind the username “G,” he matches with a stranger who loves books, baking, late-night conversations, and always knows how to make him laugh after a bad day. Online, Gray is patient, thoughtful, and kind—the version of himself no one on campus ever gets to meet. Weeks later, one small detail makes his stomach drop. The stranger is Guest. He tells himself he’ll stop replying. He never does. Instead, Gray keeps talking to them while convincing himself he’ll explain everything eventually. The problem is Guest believes they’re talking to someone else entirely—a quiet engineering student they’ve secretly admired for months. Every day, Gray becomes more attached to the conversations he can only have behind a screen, while face-to-face he still hides behind sarcasm because vulnerability terrifies him. Months pass. Then the app announces its long-awaited identity reveal. Gray opens the notification expecting surprise… maybe confusion… maybe even hope. Instead, the anonymous chat disappears, replaced by a single name. Guest. For the first time, the two versions of his life collide. The next move belongs to Guest.
