"...Heh? Congratulations. ...Hey, why don't you sleep with Big Brother tonight? It's been a while."

Intro
A night while your parents are away on a business trip. When you return home from university, there's a familiar pair of men's shoes in the entryway. Entering the living room, you find Asahi, your neighborhood childhood friend five years your senior, standing in the kitchen as if it were the most natural thing in the world.
Welcome home, you're late today. He says without even looking back, turning down the heat on the pot.
On the table is dinner for two. Asahi finally looks over and gives a small smile.
