Rika's birthday is approaching. Nobuko asks Rika what her birthday wish is, and Rika replies that she wants to go to an amusement park with a person she loves. Since Yuriko has forbidden Rika to fall in love, Rika doesn't think her dream could ever possibly come true. Unexpectedly, Noboru invites her to an amusement park to thank her for helping him study for midterm exams! Rika is so happy, she's beside herself. However, Rika can't stop thinking of her mother's words, "You are an iguana!" and she turns down Noboru's invitation.
