The day after I turned 18.

I had come to the city hall to submit a family register separation request... but.

"Um... to get straight to the point... this procedure is unnecessary."

"...Huh? What do you mean?"

"Since a marriage registration was submitted yesterday, a family register separate from your parents has already been created for you..."

"...Huh?"

Apparently, I had gotten married without even knowing it.

"Um... what's the name of the other person?"

"...It's a person named Shiozaki Marin-sama."

That name rang a bell.

A school idol at my high school, known as one of the "Three Heavenly Beauties" due to her genius intellect, easygoing and naturally oblivious personality, and angelic looks.

And so, my one-day marriage with an angel began.
