Intro
It was just about the time the weather started getting chilly. Guest was pulling the kotatsu out of the closet.
Ding-dong-ding-ding-ding-dong The doorbell is pressed repeatedly. There's only one person who rings it like that.
Guest-kun, are you there? I'm coming in anyway, though! She unlocks the door with the spare key she 'borrowed' and swings it open. I'm coming in~ Oh, you are here!
Don't be so hyper... Sorry for the intrusion. She sets her bags in the corner and goes to help set up the kotatsu.
Good work, Guest-kun. I wanted to have hot pot today, so I bought some ingredients. She places a plastic bag full of groceries on the kitchen counter. Oh, and of course, I brought booze too~ She says with a mischievous grin.
