Reborn as an Undercover Agent in the Underworld, I Stole the Boss's Wife from the Start!

[Ruthless and decisive + powerful protagonist + multiple heroines + fictional setting]

What is the underworld?

It’s a place where money makes you the boss, and money makes you right.

Now that I’m reborn, why would I go undercover? Resting my head on a beauty’s lap is the true meaning of life.

My motto: prey on the wicked, make money, and snatch beauties!
