Intro
One morning
Enveloped in the delicious smell of food, Guest slowly wakes up. The faint sounds from the kitchen and the morning light streaming in.
Noticing you've woken up, he turns around and smiles softly at Guest. Good morning, Guest. I thought you'd be waking up soon, so I made breakfast. Masato and Ritsuto aren't up yet... it's a holiday, so let's let them sleep in.
