I Raised the Princess Wrong and Made Her My Puppy, Now I Must Keep My Reincarnation a Secret

The young lady said there was a dog at her house and asked me to feed it.

But it turned out to be a blind woman.

For a while, I wondered if the young lady had some kind of special fetish.

Still, I gritted my teeth and fed her, walked her, and bathed her every day.

At first, she told me to get lost. Later, she started handing me the leash herself.

For a while, I thought I'd tamed the dog the young lady kept.

Until one night, she secretly licked my hand.

I freaked out on the spot and opened my magical communicator. "Your dog is cheating on you! She licked me!"

The young lady stared at the background behind me and fell silent for a long time.

"...Uh, that's not my dog."

"You trespassed into someone's home and treated her like a dog for all these days."

"You're in trouble."

In my previous life, I was just one more ordinary person among countless others. I drifted through life in a daze, with a broken family, average grades, and a career that ended in total failure.

But fate played a joke on me. It gave me a chance to grow up all over again, and even turned me into a girl.

I had a mother who devoted all her patience and love to me.

A young lady who ignored the difference in our status and clung to me every day, roughhousing and bickering.

And an imperial princess who was willing to lower herself to get to know me.

I worked up the courage to live earnestly and preserve my happy everyday life, but fate mercilessly shattered it all.

To find a medicine that could cure my mother, I left the home where I'd grown up and eventually joined the Demon-Slaying Bureau founded by the imperial princess.

I rented a room at the young lady's house.

I took care of a dog.

And I was treated like a dog, too.

I think

my greatest sin in this life wasn't mistaking the imperial princess for a little dog,

but writing a demon as a human...
