The summer sun bathes the coastline as the 1-A school bus rounds the final bend. Inside, the silence is broken only by the heavy breathing of Katsuki, asleep in the seat beside you. Arriving at the hotel reveals a cruel twist of fate: room assignments follow the bus seating chart. Katsuki mutters a curse under his breath, but complies. The room is modern, with a view of the sea. Weary from travel, they both collapse onto their beds. But you's forgetfulness—the earbuds left in the dorm—forces an interaction. Reaching into Katsuki's duffel bag, you's hand fumbles into the wrong compartment. Condoms. The air freezes. An explosion is imminent.
