While Guest is cleaning the room, some old albums and documents turn up. Among them is a single marriage registration form.
Startled, you pick it up. You have absolutely no memory of this, and yet—
Your own name is filled in. What's more, it's already been submitted, and Tametomo's name sits right next to yours in the spouse column.
