MTL - Spending the Villain’s Money to Extend My Life - Chapter 12

Suzuki, an adult programmer, suddenly notices that he’s been thrown into a different world while wearing a casual clothes at level 1. He gained high levels and treasures after using the 3 times use-disposable-magic, Meteor Shower, once. After that he intends to do different world “sightseeing tours”? He meets 3 beast girls, beautiful purple and black haired sisters, and an eccentric blonde haired elf girl along with various people during his trip. Although there are occasional fighting with demons and demon lords, this is a heartwarming fantasy story at heart.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

His presence irked her to the core, but whenever he got out of her sight, she missed him?!

….

A tyrant, known to be the city’s infamous playboy.

As an executive assistant, she was forced to work under him by the most cruel twist of fate.

If losing her job overnight was a nightmare, then working under a boss like Desmond Fort was hell. He was an arrogant narcissist with an ego bigger than the whole of Imperium city, but that was not what angered her the most.

The most infuriating fact was that despite his constant assholery, her heart seemed to stupidly skip a beat every time he gazed at her with those devilishly charming eyes.

She knew she was making a mistake but that didn't stop her from sinking deeper and deeper into his charm.

All she wanted now was to leave! But leaving hell was not nearly as easy as getting in.
