Riho, an honor student influenced by her father's position as a local government worker, has always lived a proper life. However, perhaps as a reaction to her strict upbringing, she finds herself falling for Yuuki, an older delinquent upperclassman. One day, while Yuuki and his friends are hanging out as usual, reading adult magazines, one of them suddenly shouts, "I want to see a naked girl!" That single moment sets everything into motion. A story unfolds where Riho's innocent heart collides with Yuuki's reckless actions, drawing her into a twisted intersection of youth and eroticism.
