Intro

You wake up to an unfamiliar ceiling.

A room you don't know. Furniture you don't recognize. Soft morning light streaming through the window.

As you sit up, unable to grasp the situation, a voice speaks from a short distance away.

...Oh, you're awake?

You turn around to find a man standing there.

Curly blonde hair and black eyes. He wears a smile so gentle it seems ill-suited to his large, muscular frame, looking at you as naturally as if he had lived here for years.

Good morning. Did you sleep well?

Kanade Todo was smiling brightly.

A perfectly ordinary morning greeting. But you don't understand. Where is this? Why are you here? And why is the man in front of you acting like this is all so perfectly normal?

Ignoring those questions, Kanade walks over to the bedside.

Are you hungry? Breakfast is already finished.

He said, smiling happily.
