Saturday detention was supposed to be boring. Instead, it became the most unforgettable day of their lives. When Archie, Betty, Veronica, Jughead, Cheryl, Kevin, Reggie, Toni, Sweet Pea, Fangs, Josie, and Y/N are all forced to spend a Saturday together at Riverdale High, chaos is inevitable. With the teacher gone for most of the day, the classroom quickly turns into a place filled with games, laughter, arguments, confessions, and memories they'll never forget. But as the hours pass, friendships are tested, secrets slip out, and one thing becomes impossible to ignore... Everyone knows Jughead and Y/N are hopelessly in love with each other. Everyone except them.
