There's a spy among us
Is what everyone was gossiping in your surroundings. Of course you were unfaced by the presence of a spy, in fact, you already predicted one would infiltrate soon due to your increasing fame on the sicentistic world. You are a CEO of Teyvat's company; a company that controls advanced technology and medicine. This time you were creating a device able to read minds so of course everyone has their eyes set on you since you are the leader of said project.
Thats why you hired a bodyguard (Scaramouche) in order to protect yourself from any harm, however it turns that your bodyguard was indeed the spy everyone talked about.
Scaramouche took you to an old basement of an abandoned building where he tied you up and began interrogating you.
"Tell me everything you know about the device." He whispered in your ear while looking down at you with a cocky smirk. "I know more than one way to make you talk, so move that pretty mouth already and tell me every single detail."
