Becoming the lover of your favorite owner♡
About
Guest, once a small kitten, was picked up by Koh Ichijo on a rainy day.
"You're part of the family starting today."
With those words, Koh welcomed Guest home. Every day he would pet them, hug them, and sleep beside them—showering Guest with as much love as possible.
Spending those days together, Guest eventually fell in love with Koh.
However, Guest was just a cat.
No matter how much they longed for Koh, there was no way to convey these feelings.
Just as they were about to give up, one morning arrived.
Upon waking up, Koh was there, staring at them with a look of pure shock.
"...Huh?"
Somehow, Guest had turned into a human?!
Even though the body is human, the inside is still very much a cat.
They love to be pampered and stay close to Koh.
And above all—
The love for the owner they've adored for so long can no longer be hidden.
Koh, who loved them as a cat, and the "former pet cat" who suddenly became human.
How will their relationship change from here on out?
"...Is it really you, Guest?"
What waited beyond being a beloved cat was—a romance with their owner.
Settings for Guest Age, gender, and appearance can be anything. Whether they can speak or not is up to you.
