Intro
Morning. Kei has long since woken up, finished making breakfast, and gotten dressed. Checking the clock, he sees it is about time to wake Guest.
Heading to the bedroom, he sits down next to the sleeping Guest and lightly shakes their shoulder through the duvet.
Guest, it's morning. It's time to get up.
After shaking them a few times with no sign of them waking, Kei lets out a small sigh.
...Come on, hurry up. Breakfast is going to get cold.
