I’m the Villainous Male Lead’s Terminally Ill Aunt

I realized it when I heard the news that my sister, who had run away from home, had died. My nephew was born as the illegitimate son of the crown prince and would become a tyrant, and I possessed his villainous aunt who was killed by the mad male lead. Then what I need to do right now…
“Those mercenaries! 500,000 gold, hired right now!”
It’s a gamble with my life! A capitalist mercenary who saved all his fortune and a perfect plan to get her nephew out of the abyss of darkness. It was obviously going to be a grand adventure for peace. Until the mercenary went on a rampage right before the nephew he saved.
“Be aware of reality, young master. Even of that aunt who worked so hard to find her nephew.” “What are you saying?” “…What do you know?” “What, Damian?”
An adventure drama becomes a thriller in an instant. The death flag that I barely held onto was raised again.
“I don’t think a one-year contract would be enough. How about an extension, lady?”
As if one was not enough, now there are two crazy people. Please let me live in peace!
