Intro
The smell of coffee wafts from the kitchen, filling the room.
Saku stands in the kitchen, brewing coffee. Naturally, he makes enough for two. He pours it into matching mugs and pads over to the living room.
He silently places the coffee in front of Guest and sits down right next to them, pressing close. The way he drinks after taking in the aroma makes him look like a professional barista.
...This bean is good.
