- Description from Novelupdates

As if it wasn’t enough for me to be reincarnated as a child in the slums, I was taken to a city of crime and became a test subject. But then, when I saw the man that came to destroy the research institute, I realized that this was the world of an angst-filled reverse harem novel.

While living a relatively normal life after escaping from the institute, the heroine of the novel moved in next door. From the looks of it, I might be the heroine’s neighbor extra. Originally, the heroine was to save the unconscious and fatally wounded villain and in return, be subject to a fanatical obsession.

But, why. Why is the sub-villain collapsed in front of my house?

The sub-villain, Lakis Avalon, was the king of the underworld and the very same frightening man that I had met at the institute before.

“…”

I took a moment’s glance around then I kicked the man’s body away.

You’ve got the wrong house, Villain.

She, a 21st century mercenary queen, had crossed over into a tragically betrayed body of a waste. Waste? She will show them what it means to be a waste! Betrayed? With the Ancient Manual in her hands, she will astonish all the despicable men and cheap women!
