I was a regular guy.
I had a regular job.
A regular family.
And, although I was still a bachelor, I had been in several relationships, although none of them got far enough to lead to marriage.
Then, I was stabbed in the back.
I didn't even get to see their face before everything blacked out.
'Why was I killed? I just lived a normal life!'
Then, I woke up in a baby's body.
At the age of 10, when we were finally getting our status windows, I suddenly realized something.
When I looked at my twin sister, I almost choked from shock.
'Fuck, don't tell me I got reincarnated into "that" novel!'
'And furthermore, I'm the main villain, the villainous brother!'
This is the story of my quest for a lazy life, one where I didn't have to do anything. I just wanted to live a lavish life as the son of the duke, my sister could do whatever she wanted and save the world, and I wouldn't interfere.
At least, that was what I thought at first.
