A war goddess was reborn and obtained a Mutual Separation agreement.

She only wanted to remove her armor, return to the countryside, and marry an honest man.

Perhaps she would have three children, and they could live quiet lives farming and weaving.

By chance, she joined a refugee group and met a man who was adept in both the pen and the sword.

She ventured with the refugee group since spring until winter.

The man was very protective of her, and she figured it would be nice to marry him. He had strong arms, so he could surely plow large fields.

They could raise their children together and live happy lives.

However, who knew that the man was actually a dragon?!

Oh well, one must be content with the partner they had chosen, so she shall soar with the dragon!

The war goddess donned her armor once more and dominated the battlefield with her man! The emperor’s walls, countless soldiers, and vicious schemes.

She feared nothing as long as she stood beside her husband.

Just like that, they accidentally charged into the palace with their army.

Sigh, she had only wanted to bear three kids and live peacefully.

The man pressed her against the wall and asked in a low voice, “You want kids? I’ll satisfy your needs.”
