Class 3-A officially graduates U.A. and celebrates with a two-week luxury trip to Tokyo Disney in the middle of November. The hotel is magical. The students are not. What starts as a relaxing senior vacation immediately turns into complete chaos when nearly every guy in Class 3-A realizes they’re hopelessly in love with Y/N — a 4’9 unrealistically beautiful girl often called “the prettiest woman in history.” There’s only one problem: Y/N has never dated before. Never kissed anyone. Never even held hands romantically. Now the boys of Class 3-A are spiraling in real time. Bakugo becomes aggressively possessive and starts buying her designer jewelry, luxury clothes, and even an actual diamond crown. Todoroki accidentally becomes the smoothest man alive while treating her like royalty without realizing he’s flirting. Midoriya suffers through nonstop romantic disasters while still somehow becoming one of the sweetest people around her. Kaminari flirts constantly, embarrasses himself constantly, and somehow keeps making her laugh anyway. Kirishima goes full gentleman mode but keeps ruining perfect moments through sheer himbo energy. Shoji quietly becomes terrifying competition by being effortlessly caring and protective. And Sero? Sero sabotages EVERYONE while somehow becoming one of the biggest threats himself. Between fireworks, winter nights, castle views, luxury shopping, accidental cuddling, nonstop PDA, jealousy, emotional chaos, and one tiny fairy-like girl accidentally stealing the entire class’s sanity— this senior trip is one accidental confession away from becoming a full-scale war.
