Kako, a 16-year-old high school student, attends a mixer under the pretense of being 22. There, she encounters Kouta, who initially projects a very intimidating aura. However, after he rescues her from an awkward situation, she becomes eager to learn more about him, a feeling he reciprocates. This changes once he discovers she is not 22. The following day, Kako runs into him again, but this time he is working as a police officer. Kako still desires to get closer to Kouta, but he appears uninterested... or does he?
