MTL - Lord Highlander - Chapter 17 16. Army life

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.
I had no idea about what I have done.
On May 1st, Conan ‘the God of Death’ came to my house. I was forced to let him in and we get involved in a criminal case.
On May 8th, Bruce Wayne ‘Batman’ came to me. I was forced to follow him to fight crime.
On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.

- Description from Novelupdates

A world where all of the greatest in all dimensions have gathered.

Three out of five were the strongest in their world, and one of them was considered the strongest in history.

A crazy world where a wandering goblin would be above level 90.

Asgard, otherwise known as “Heaven above the heavens.”

In a world where all of the monsters of the worlds meet, Vulcan’s new adventure begins.

# endoftheyearJi Yuanyuan was the type of person who would ruin a nicely dealt hand. She could have led a carefree life under her family and ex-husband’s protection. Alas, for the sake of a scum named Zhao Tianhua, she caused her mother to die an aggrieved death, her eldest brother to die in a foreign land, and her second brother to be run over by a car and had his head disembodied. She herself even died from childbirth in a shabby house at the countryside, and her baby was strangled to death by Zhao Tianhua. It was right before her death that she learned that her quiet ex-husband almost went mad searching for her.Ji Yuanyuan was reborn back into the 90s era with extreme luck and a mysterious spatial ability. Since then, Ji Yuanyuan would find money on the ground, boars would run into trees on their own if she was lost in the wild, and her investments would all be successful… When the b*stard scum, Zhao Tianhua approached her again, Ji Yuanyuan kicked him away and latched onto her ex-husband’s leg instead. “Sir, please protect me.”

I transmigrated into a novel and became the villainess, Serina who comes from the noble Ducal Melford family.

As a well-to-do character, I tried to mind my own business, but the story had other ideas. A self-proclaimed mother brought back a boy – the duke’s heir and a genius wizard – intent on brainwashing and blackening him.

The contents of brainwashing are two things:

1. Obey our family.

2. And fall in love with Serina.

Thanks to that, the brainwashed twisted yandere is obsessed with me…

I can’t do this. I have to undo the twisted character’s brainwashing!

By the way, what’s this situation?

“Now that the brainwashing is gone, I’ll do as I please. So Serina, please, let’s do our best.”

I’ve solved his brainwashing… but why does he seem even crazier than before—

Did I make a mistake?
