The Rational Detective in Detective Conan - Chapter 88: Sodium Hydroxide Poisoning

Once upon a time, a hero had been summoned to a different world in order to defeat the demon king. After the war stretching 3 years ended the commendable hero slew the demon king. And he was forcibly deported back to earth after being dismissed.

Such bullshit!

Elves in addition to beast race, dwarfs and demon race. Even though I wanted to make a harem in the different world I saved! My dream will not come true on earth, where there is no magic at all. Thus, the hero returns on his own. Without the blunder of being extradited to earth this time, he will build a harem of his own in a different world.

"Your bed is cold," spoke a voice in the room that had her eyes go wide in fear. Nervously, she turned around, gulping softly to see a shadow on her bed as if someone laid down there. The man who had been lying down sat up emerging out from the shadows where he had been waiting for her.

~She is a waste daughter from the Su family that couldn’t cultivate. On the day before her wedding, the Third Prince breaks off their engagement in the street. Her own sister replaces her in the marriage to the Third Prince. She became the center of gossiping in the city. In her resentment, she hits herself on the Su Family’s gate, only to become the object of other people’s ghost marriage.

She, Su Zimo, open her eyes to find herself sleeping in a coffin. It’s not to surprising seeing as she put herself here (hit head on gate), but why is there another person lying beside her? And whats more they are wearing red wedding clothes. After taking all this in she almost faints.

~He, is a cursed person with an indescribable status. This curse that has been passed down in his family for centuries is now effecting him.

A mistaken ghost marriage, a battle in business, and a long period of painstaking love, made their fate intertwined.
