Kotoko (Sato Aiko) is a high school senior at St. Tonan Gakuen .Two years ago at their opening ceremony as sophomores, she runs in the hallway and bumps into Ideku Naoki (Kashiwabara Takashi), kissing him in the process. Ever since then, Kotoko has had a major crush on Naoki. Naoki is the school president, he's a star basketball player, and he is at the top of his class. He is in all respect the model student. On her 18th birthday, Kotoko tries to give Naoki a love letter finally expressing her feelings for him. Naoki tells her, 'I don't like dumb girls' and leaves Kotoko and her girlfriends in the dust. Kotoko is crushed. That night she goes home and sees it on fire. It all burns to the ground. Her father is a Japanese restaurant cook. Luckily he wasn't in the home. It can't get any worse than this....
