I couldn't sleep.

I don't know why.

An indescribable loneliness.

Still, as I closed my eyelids, my consciousness slowly began to sink.

That was when it happened.

--- Don't worry.

Suddenly, I heard a voice.

A warm and gentle voice.

A mysterious voice, sounding like both a boy and a girl.

--- This time, I will love you so much.

With those words, my consciousness fades.

And then...

"...Huh...?"

I open my eyes.

An unfamiliar ceiling.

An unfamiliar room.

An unfamiliar city.

Unfamiliar people.

At this moment, Guest did not yet know...

That this person, known as a Demon Lord, would become their adoptive parent.
