Death March kara Hajimaru Isekai Kyusoukyoku (WN) - Book 2 - 2-4. The Afternoon Date with Soldier-san

The prostitute of the Feng family was actually reduced to living in a haunted house.

At first, everyone thought that she would cry, make trouble, and hang herself, but she was quiet every day, without making noise, and set up a fortune-telling stall to earn living expenses.

A few months later, everyone in the Feng family invited her back.

She smiled and shook her head. Going back to the Feng family, there are no female ghosts to do housework.

Behind him, Lord Wei, who is the master of the city, aggressively embraced his fiancée in his arms, “My wife is timid, don’t scare her.”

All the ghosts who were caught, “Are you talking nonsense?”

Just when everyone was waiting for Master Wei to cancel his marriage with his nominal fiancée, they actually waited for the news of their engagement.

Outside the nickname, Master Wei married Miss Feng’s family.

Impossible, Mr. Wei is ascetic, mysterious and low-key, never letting women come within one meter of him.

Master Wei was full of smiles, “Nian Nian, where do you want to go to catch ghosts tonight?”
