Living together with my ex-husband?

Sarah never thought she would one day meet Michael, her ex-husband, again in the operating room with his body full of wounds and needing treatment from her.

They were already divorced for three years, and Sarah didn’t have a good memory of the man. If she could… she would have let him die. However, she was a doctor, and a doctor's job was to save patients.

Sarah immediately regretted her decision to save the man because it turned out that Michael had amnesia and remembered that they just got married!

To make matters worse, she stupidly accepted her ex-in-law's request to pretend to remain Michael's wife while taking care of him. Why did she do that?

However… during the time she spent with her ex-husband, Michael's attitude was very different from what Sarah had last remembered. He was very gentle… and loving. It made the feelings she thought were gone, come up to the surface.

Would Sarah be able to deal with her feelings? What would happen when Michael's memory suddenly returned? Would his attitude stay the same?

=============

EXCERPT:

“Wifey,” Michael called, looking at Sarah who was lying beside him.

“Hm,” Sarah answered curtly, not looking at Michael.

“I think I'm healthy.”

Sarah's body stiffened when she heard that. Was Michael healthy? Did that mean he had remembered everything? Would he scold her for tricking him?

“Wifey? Why are you silent? I think I'm healthy and I can do it,” Michael said quietly.

“What do you mean?” Sarah finally looked at Michael with raised eyebrows. “Do what?”

“Making babies.”

When humans step into the Galactic Era, the ancient art of cultivation thrives once again.

Long Fei, a cross-timer and doujin, is an otaku who traveled to another world. In the original world, he was an otaku fan of Gundam and military science fiction.

He died in an accident and was reincarnated into another world. The Gundam works he had read before his death and the techniques in various military novels could be brought to another world.

How would he use the Gundam that Long Fei created? What waves can be caused in this different world?
