Cultural Invasion In Different World - Chapter 1020

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.
