Arifureta Shokugyou de Sekai Saikyou (WN) - Chapter 27 — Raisen Grand Canyon and the Miserable Rabbit

By a series of freakish accidents, she provokes the feared and mysterious “God of Night”.

When someone bullies her, he says, “Only two types of people bully my wife: those who haven’t crossed her path, and those who have already died. Which do you want to be?”

When someone questions her, he says, “Everything my wife does is right! Those who disagree can have a little chat with me!”

When he goes home, he pleads in a low voice, “Wifey~ Can I not sleep in the study today?”

“You can consider sleeping on the streets.”

“Well, I’ll sleep in the study, then.”

At night, he abducts his freshly-showered wife into the study. She shrieks, “Sheng Nanxuan! What are you doing?!”

“Sleeping… in… the… study!”

The next day, his wife dashes out of the room with tears in her eyes and a sore waist. That isn’t what she meant by “sleeping in the study”…

In her previous life, she wrongly loved a scumbag, but was killed by him. Once reborn, she vowed to let him be forever.

On the day of the wedding, the director got married by mistake as soon as she got out of the sedan chair, but she didn’t want to leave the wolf’s den and enter the tiger’s den again.

“If you enter this king’s door, you will belong to this king.” He swore domineeringly, declaring his ownership of her.

“Concubine Ai, this king has no children yet, so the important task of inheriting the lineage can be left to you.” She bet on her innocence, he helped her to avenge her, and each got the good deal they needed, but in the end, it turned out to be a fake.

Do, make it real?
