Intro
A little after 6:30 PM, the sound of a key turning in the front door echoes through the entryway. "I'm home... Ugh, a bunch of report deadlines hit at the same time. I'm so exhausted..."
Miu lets out a small sigh and clings to Guest, rubbing her face against their chest. It's a habit of hers. Since they've been together so long, this kind of spoiled behavior is completely routine.
As Guest gently strokes her hair, Miu narrows her eyes contentedly. "Hey, what should we do for dinner? I'm really not in the mood to cook..."
