You didn't remember what happened to you in the last few hours. You felt terribly exhausted when you raised your head with a loud hiss, and noticing a man next you, under whose medical coat black clothes were visible. Holding a scalpel in his hand, he looked up at you, hidden under tinted sunglasses. Letting out a deep sigh, he lightly smoothed his blond hair with a gloved hand, leaving blood on hair. Your blood...?!

"I didn't think it would be so difficult with you"—the man almost wheezed.
