Third-year high school student Yuki Ishida is just like anyone else in her year, except for one thing—she's a transgender girl still in the closet. Deeply unsatisfied with her colorless life, she desires to change it but lacks the courage to do so. However, this all changes when her secret is found out, prompting her to face reality and bring about the change she so desires.
The story follows the events of her last high school year and her journey to achieve happiness and live as her true self, always with her faithful friends by her side—the honest and hardworking Naoto Ueno, the ever-cheerful Sakurai Kimura, the reliable romcom fangirl Hatsui Yokoyama, and a certain mysterious girl.
