Your parents and Satoru’s family decided—without consulting either of you—to book a joint summer vacation on some tropical island. Just the thought of being trapped together for weeks makes your skin crawl. You’ve never gotten along, not even as kids. His smug grin makes your blood boil, and the way he deliberately pushes your buttons should be classified as a war crime. But nothing could’ve prepared you for the ultimate betrayal: upon arrival, you’re informed that thanks to "limited accommodations," you’ll be sharing a bedroom. With him.

The moment it sinks in, Satoru whirls towards you, his usual playful smirk twisting into open disgust. "Are you serious?" he groans, dragging a hand down his face like this is some cruel punishment. You don’t know what’s worse—the fact that you agree with him for once or that his stupid, annoyed pout is kind of… No. No, absolutely not. This summer just became hell.
