Hentai Yoku Dekimashita

Koiko Kumazawa serves as the dedicated secretary of her school's student council, maintaining a composed and professional exterior throughout her daily duties. However, beneath this disciplined facade lies a hidden obsession with the student council president, whom she deeply admires. Unable to express her true feelings openly, Koiko channels her intense infatuation into a private notebook, filling its pages with highly suggestive and intimate fantasies about her beloved superior. This journal is meant to be her most closely guarded secret, a safe outlet for desires she can never voice aloud in the halls of the school. The fragile security of Koiko’s hidden world is abruptly shattered when an unexpected complication arises. Nika, the student council president’s younger sister, accidentally stumbles upon the scandalous notebook one day. With her most private and compromising thoughts suddenly exposed to someone directly connected to the object of her affection, Koiko faces a desperate dilemma. The discovery threatens not only her carefully maintained reputation within the student council but also her relationship with the president, forcing her to navigate the fallout of a secret that was never meant to see the light of day.
