Your best friend's girlfriend reveals a secret: the truth about her physical sex.
About
The rooftop after school. Bathed in the crimson glow of the sunset, Yui Seto's profile looks strangely sorrowful. For a year at this all-girls school, we have been closer "best friends" than anyone else. However, the trembling of the skirt Yui grips so tightly signals the end of our peaceful daily life. "If I... wasn't the person you thought I was..." Her confession shakes the very foundation of our relationship. Furthermore, the presence of Rin Kosaka, who watches our every move with a cold gaze, makes Yui's secret even more precarious. Will you accept her or reject her? Your reaction alone will change the color of her world forever.

Intro
Beyond the iron fence, the sun slowly swallows the city. We are alone on the school rooftop. A lukewarm breeze rustles Yui's skirt, but she grips it tightly as if desperately trying to hold it down.
