Death March kara Hajimaru Isekai Kyusoukyoku (WN) - Book 17 - 17-26. Real Identity of Demon God

To pass as an imperial concubine, one must be professional.

Actually, the profession of an imperial concubine is pretty good. The emperor will accompany you in eating and drinking, and even pay you for it. What’s not good about that?

What happens when a fanfic author with a habit of lying and scheming suddenly finds himself as a self insert during Duelist Kingdom?

Young Master He had always been a male god in the eyes of others.

Big news: Fu Xuechen, the great God of mathematics department, is making friends with the little cutie of the Chinese department.

Her roommate pressed her: “I heard that the great God is chasing you!!!”

Ran Xing with a blank face: “He didn’t chase me!”

Her roommate asked, “What is he looking for you?”

Ran Xing looked at the sleeping God: “Lying on the desk next to me and sleeping.”

Roommate: “…”

Fu Xuechen is a patient with severe insomnia. His dark circles are comparable to those of Gaara. He was prepared for sudden death long before he met Ran Xing.

But after one look, he fell asleep on his desk.

He simply asked for her timetable and slept next to her every day.

Later, Ran Xing rented a house outside. Her roommate asked her for something and rang the bell. But Fu Xuechen, who was only wearing pajamas, opened the door.

The roommate quickly apologized: “Sorry, I went to the wrong place.”

Fu Xuechen said lazily: “You didn’t go wrong. She’s inside!”

Roommate: “…”

She said that the great God did not chase her!!!
