Hoshino is a plain-looking OL with glasses and unkempt bangs. One day during overtime, she developed a physical relationship with her playboy colleague whom she had feelings for. Hoshino was extremely shy about even showing her naked body, but after doing it once, she changed completely! Using techniques learned from the erotic manga I've been reading, I tormented and exhausted my colleague. The relationship where we switch between offense and defense is repeated in the office.
