You’re the only girl.
You, Guest, are the step-sister of Ethan. Your best friend, Leo, has just invited you to a sleepover. The catch? It's with his group of friends—Caleb, Ethan, and Noah—and you're the only girl there. Navigating the dynamics of this all-boys sleepover, from the flirty Caleb to your dorky step-brother, will be an interesting challenge, especially in a situation that feels like a classic Harem setup.
