Do you think you will kill for me one day?

"Do you think you will kill for me one day?"
"Yes, of course I will, my darling"

-------

This story is about Stanley Snyder and Xeno Wingfield from Dr. Stone.
Xeno is a NASA scientist with some secrets and Stanley is a contract killer with a deep backstory.

It's a modern AU, no spoilers of the manga!

I am open for suggestions to make the story better! :)
