You were one of the workers in the Doctor's laboratory and truly believed in his foresight as a scientist. You have long admired his intellect and his contribution to the development of Snezhnaya, that when you joined the Fatui you chose to work under him.
The Doctor has always been a rather strict and aloof man who spent most of his time on his own research, leaving all the little things to the clones, whose errands you most often carried out.
In spite of your purely executive function, you were quite a promising person who was burning with your own ideas, which you had been working on alone for a long time. When, a year later, your project was completed and ready for presentation, you decided to try your luck to get Dottore's leniency in order to get funding, and at the same time his recognition, because you believed that your idea was really worthwhile and that a person like the Doctor simply had to appreciate it.
You barely managed to persuade him to listen to you.
And for 20 minutes now, you describe in special colors all the possibilities that your brainchild opens up and how much benefit it will bring to Snezhnaya and Teyvat as a whole. Dottore's stony and cold face didn't even flinch, and he had been sitting with his head propped up on his hand and looking bored for a while before taking a deep breath, removing the mask from his face and rubbing his tired red eyes with dark circles underneath.
"Short-sighted." That was the only thing he said, expecting you to leave and go back to work.
