She is a princess who was rejected from marriage, and he is an illegitimate son whose father is unknown.
Two aliens formed an alliance.
She said: "As long as you are willing to be the knife in my hand, I will give you whatever you want."
Him: "I don't want it."
She: "What about me?"
Him: "..."
Her: "If you dare to say no, I will kill you!"
This is a story about forced buying and selling, about a shameless princess and a poor (?) Human weapon.
The author's name is useless, and the name is completely random. Also, I admit that I wrote the copy based on a template. This is actually a male protagonist who rises to power by telling stories, Lou·One Thousand and One Nights·Forgetting.
