“I’ll fix your dress according to your taste this instant!”

“My request.”

“O-Of course! As per your request, there’s only one piece available in the whole Empire.”

“Why don’t you give me the honor of escorting the Princess?”

I have had enough of dealing with my father, so why did an unexpected character suddenly appear? What if this person disrupts my plan?

She’s a total idiot, too carefree, and her sense of personal space is completely broken. To Nao, she’s supposed to be nothing more than a nuisance, and yet...

“At first, I hated her for sure. She was noisy, and always took the things I cherished. So why is it that now—?”

Even as he grumbles about her constantly calling him “Lil bro," he finds himself unable to leave her alone. How did this “annoying” fixture in his life become the one person he can’t look away from?
