After a prank goes wrong, Y/N and Mattheo are assigned detention together every Saturday for six months. They spend the first few weeks arguing. Then the arguments turn into conversations. Soon, detention becomes the one place neither of them wants to miss. The problem? Mattheo has a girl constantly hanging around him, and everyone assumes they’re together—including Y/N. By the time Y/N learns the truth, they’ve spent months pretending they don’t care about each other when everyone else can see they do.
