She was there only for a blind date, but had been mistaken as the third person to seduce the men. She angrily cursed, “I don't know that scum!” As a result, she had been pestered by this “scum” ever since.

She became his wife because of an agreement of “secret marriage”. They clearly said that they wouldn't touch each other, but this Mr. Huo actually went back on his word in the blink of an eye.

One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive.
