MTL - The Demon King Always Thinks I’m Secretly In Love With Him - Chapter 16

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.

Venshiro, a young ronin bound to the Black Vein Blade, is hunted by clans who would kill for the curse he carries. Every time he draws the sword, it takes something from him—his memories, his soul. But the blade remembers everything.And now, it wants more.

Aaron, a wildlife biologist, became a military strategist right after a global war between nations began.He never wanted to participate in the war but he had to, because he wanted to continue his studies on endangered species the moment the war was over, but to his surprise, everyone in his unit were killed, including him, and the next thing he knew, Aaron woke up in the body of a young noble having a similar name to his.However, he also noticed he had awoken in a world different from Earth.In this world, demonic beasts ran rampart with only one thought in mind, causing them to feed on anyone they see, be it humans, elves or even magical beasts as well.During his first encounter with a magical beast, Aaron awakened a system which allowed him to bond with magical beasts and to obtain terrifying abilities from these bloodcurdling magical beasts, so he used his experience as a wildlife biologist to help make it easier for him to bond with these beasts.However, Aaron also noticed he could evolve these beasts if their loyalty towards him had reached a certain level, so he vowed in his heart to grow strong enough to protect those he cared about in this world with the hope of living a happy, peaceful life where he'll be able to focus fully on his passion as a wildlife biologist.

He Zening had always felt that novels depicting the life of a Company President were good for passing time, but insulting to the IQ. Still, having read countless novels of this genre, never did she imagine that someday she would transmigrate into one of them. To make matters worse, the plots were so similar that she could not remember which novel it was. She was left with no choice but to assume the role of a secretary to the President.

The secretaries in novels ran errands for the President, assisted him in pursuing women, helped him keep the flames of love burning, and even took the blame for him if necessary. But a real-life secretary? They were blamed by those in power, sometimes hurt and reprimanded wrongly.

If it were not for the excellent pay and necessity, she would have already bolted out of the door. And like all curious bystanders, He Zening wanted to see the plot happen before her eyes; the President meeting the protagonist! A villain standing between the love of the leads! The side characters!

This is the second life of a level-headed, diligent secretary working hard to achieve a carefree life, whilst being dragged into the plot.
