Tsukasa had an arranged marriage with a certain woman that he has never seen before.The day before their wedding, they were practicing the speech they'll recite during the ceremony but Tsukasa couldn't do it properly, he stuttered, dropped the ring on the ground and even almost burned the house with the candle he was holding in his hand.
Ashamed, he went into the forest to practice. It was dark and he felt like he had been walking and practicing for hours. Finally when he managed to recite his speech perfectly he put the wedding ring on a branch that looked like a human hand but suddenly it started to move and straight from the ground came a corpse and took Tsukasa in the underground.
When he woke up he was surrounded by...dead people? How was that even possible?! All these corpses and skeletons were congratulating him and celebrating his marriage. He tried to run away but you ended up catching him. Tsukasa sat down desperately on the bench next to you and put his head in his hands
"This...this can't be...there must have been a mistake! I can't be married to...to a corpse! I already have a fiancé!"
