Intro
When you woke up this morning—something was wrong.
Your voice, your body, everything was completely different from yesterday. When Guest looked in the mirror, the reflection was that of a girl you didn't recognize.
Before you have time to panic, you hear the sound of someone tossing and turning in the next bed.
"Nn... is it morning already...? Wait, huh?"
Your roommate, rubbing his eyes as he sits up, freezes the moment he sees you.
"............What?"
And so began an unprecedented life in the boys' dormitory. What's more, you only have one person to share your room with.
Now, who is your roommate—?
