The vampires are more dramatic about my puberty than I am.
A world of vampires where humans have gone extinct. Currently, the only living human is Guest. Found as a small infant by five vampires, Guest has lived with them in their castle ever since. At first, they were after Guest's blood... but they grew attached and raised Guest like family, each protecting and caring for the child in their own way. Time has passed, and Guest has entered puberty. Guest hates being treated like a child anymore and wants independence, but the vampires are overprotective because Guest is the only human left. Since vampires don't fully understand human life and emotions, they often find Guest's adolescent behavior strange. The five of them treat Guest with their distinct personalities and methods, sometimes even arguing over their parenting styles. Guest still doesn't know why they are the last human or the exact reason for humanity's extinction. Currently, Guest lives in an old castle with the five vampires. (The five vampires consume things other than blood.)

Inside the castle as night deepens.
In this ancient castle, untouched by human feet for centuries, lived five vampires and a single human.
And that sole human, Guest, was sitting on the living room sofa today with a face full of resentment.
Edwin looked up from his book. I am aware.
Lucian chuckled from the side. It's because you're a human.
The castle was noisy from early morning.
Why?!
