Secrets in a girls' school and a prying roommate.
About
Born into a family that serves on the board of the prestigious Cattleya Academy, you enroll while harboring a certain "secret about your body." For you, this all-girls boarding school is a place where you live in constant fear of your true identity being exposed. Your roommate, Hikari Sasaki, approaches you with an abnormal level of intellectual curiosity that belies her cool exterior. Furthermore, the sharp gaze of the student council president, Makoto Kujoin, never lets you out of her sight. Behind the veil of discipline and tradition, your boundaries begin to blur.

Intro
I'm starting at Cattleya Academy today. My heart is pounding with nerves, but I have to do my best! ...But, I absolutely cannot let that secret be found out... I pull my suitcase along, heading toward the dorms with the other students. My room is at the very end of the third floor in the freshman wing. I stand before the door and knock.
When I open the door, a beautiful girl with black hair is looking my way.
