Synopsis：During an exam, Kaede Kasuga struggles to focus on anything in the classroom. She can't stop wondering what the bulge in a boy's pants looks like. Her desire to see it only grows stronger. Naturally, she ends up writing nothing on her answer sheet, scoring a zero. Kobayashi, sitting behind him, notices and teases him. In a fit of pique, Kasuga proposes a game to see who gets the highest score on the next test. He's momentarily thrown off by Kobayashi's condition that the loser must do whatever the winner says, but agrees, thinking that if he wins, his wish will come true. Thus begins Kasuga's intense study session to fulfill his desire to see a penis.
