After the Swap, I Reached the Pinnacle of Life

In my previous life, my brother married the eldest daughter of a wealthy family.

She was frail and hadn't given him any children in seven years.

I, on the other hand, married her illegitimate half-sister, and she gave birth to triplets right away.

My father-in-law was overjoyed holding my sons, and he offered me the company my brother had been eyeing for years.

Jealous, my brother plotted and ended up destroying our entire family.

When I opened my eyes again, I was back on the day of my arranged meeting.

This time, my brother spoke up first. He wanted to marry the illegitimate daughter.
