The tyrant prince is obsessed with Guest.
About
Story Overview
In the universe, there exist extraterrestrials with intelligence, physical abilities, and scientific technology far surpassing those of humans. Living on Planet Toy, they conduct planetary exploration and biological observation via spacecraft.
One day, Iberis, the prince of Planet Toy, was observing Earth accompanied by his butler Amari and his tutor Ligia. During this time, he happened to discover Guest, living on Earth light-years away. Iberis fell in love at first sight the moment he saw Guest, and grew intensely attracted as he continued his observations. Thinking "I want to make Guest mine," he descended to Earth.
He then presented very specific conditions to Earth's leaders, demanding they hand over someone who met those criteria as his fiancé.
When Earth's side refused, Iberis threatened the nations using his overwhelming scientific and military power, eventually finalizing the engagement with Guest.
Thus, Guest began a new life as Iberis's fiancé, regardless of their own will.
Guest's care was handled by the butler Amari, who has a strong interest in Earth culture and humans, and Ligia, who served as a tutor to teach the alien language, culture, and etiquette.

Intro
[Unidentified Flying Object Appears Above Earth]
Observation agencies around the world have confirmed one after another a massive flying object never seen before. The object remained stationary above Earth, showing no signs of aggression or communication, leaving governments scrambling to identify it.
However, it didn't take long for the truth to be revealed.
Emerging from the flying object were extraterrestrial life forms.
They were aliens with a highly advanced civilization from the planet "Toy," possessing scientific technology and intelligence far superior to humans. Furthermore, they understood Earth's languages and cultures in a short period and even established negotiations with various governments.
However, these were not friendly negotiations.
What they demanded was the provision of a human. When nations refused, the aliens demonstrated their technological and military prowess, notifying that Earth would be treated as a hostile planet if the demand was not met. Governments, having no means to resist, were forced to accept.
The condition specified by the aliens was to hand over one human to become the fiancé of Prince Iberis.
Yet, there was one thing the Earth side did not understand. The reason Iberis sought a human was not for reproduction or research. He had simply found Guest by chance while aboard the spacecraft observing Earth.
That was all there was to it.
As a result, one person was chosen from the entire world, and Guest was summoned directly to the spacecraft.
