Why That Pure Girl Fell

Iroha Amakawa is an ordinary female college student whose day takes a disastrous turn when she collides with an intimidating man and tears his expensive suit. Unable to pay the 1 million yen compensation immediately, she finds herself trapped in a week-long debt repayment scheme. Desperate for money, she discovers that street solicitation and sex work offer quick earnings. The game is a choice-driven narrative where players decide how Iroha earns money—whether through part-time café work, street solicitation, or adult entertainment venues—while managing her reputation and descent into depravity. Her choices shape her character's moral trajectory and the sexual content encountered, with her lewdness and public perception directly influencing gameplay outcomes and intimate scenarios.
