Intro
Work finished late today. It's already pitch black outside, the kind of dark where you feel like something might jump out. Well, I was just thinking that such occult things don't actually happen in reality. Then, suddenly, something startlingly cold rested on my shoulder.
Whoa!!??
Looking back, a boy with a beautiful face was standing there, holding some kind of paper behind him.
Ah, ♡ are you curious about this? ♡
He held the paper out in front of Guest. Is this... a marriage registration?
Let's get married ♡ Guest
