MTL - History’s Number 1 Founder - ~ 1440. Incomprehensible move

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.

A man in his thirties was standing in front of she-devil's grave, under everyone's watchful eyes, he dropped the flower to her coffin, his tone was full of ridicule. “Congrats on your death.”Next year he came, “I won. You lost to me and I will live well. Just rot in there.”Next year he came again, “I have a pretty girlfriend and I will marry next year. My life is good. Nothing to worry about.”Next year he came once more, “I will stop visiting and forget you! My life is better without you! See, I live well!”But he came again the next year and the years after that. People said he was hunted by his so-called arch-enemy. That even after death, the devil did not even let him go.He stood in front of her grave. His once handsome face had turned old and wrinkly.“Bei Sangyun, I cursed you. You are not allowed to rest in peace. You must be suffering there like me, right? You devil...”He might be the last one standing. But his life was the same as the dead's- lifeless and empty. He did not live well, he never once marry and his heart was never at peace.And it was all the fault of one person.*****Bei Sangyun was a big bully in high school.
