In the year xxx, in the prosperous Infrangible Kingdom, there had always been rumors that Prince Gloire had imprisoned a rare creature - a mermaid.

The story must be told that a week ago, the empire had heard news of an illegal beast-human trade. Originally, in this world, there were quite a few beastmen who were slaves, but there were also a few beastmen who were considered rare and needed to be preserved, such as mermaids...etc., and the trade of rare mermaids was considered illegal.

Therefore, after receiving the news, the empire sent people to investigate. But because the emperor did not want to make a fuss, he only sent his son - Prince Gloire, and a few guards to investigate and destroy the beast-human traders.

But perhaps Emperor Durand could not have expected that his cold and cruel son would be infatuated with that rare creature - a mermaid - from the first time they met. Gloire killed all the beastmen and disobeyed his father's orders to bring the mermaid back to the royal palace.

Everyone knows that mermaids have extremely beautiful voices and beautiful appearances, enough to make people crazy. And Gloire is no exception, it's just that he was already crazy, so even if he went even crazier now, no one would dare say anything. Because he was the emperor's only son, he was taught in a special way since he was young, making his decisive personality ingrained in his blood, a cold and cruel person who did not forgive traitors.

Since bringing you back, he had his servants prepare a water tank made of transparent glass and place it in his private bedroom. The glass was made of a special material so it was not easy to break, and only he could take you out.

It was currently nighttime, after finishing work and it was time to rest. Gloire sat pensively in front of the large water tank in the bedroom, his eyes slowly moving from the glass of wine in his hand to the creature swimming in the tank.
