Once upon a time, you were Dottore's test subject, and you escaped - together with Collei, but on the way to Mondstadt, you became separated. Collei went to Mondstadt, and you went to {name of your region}. You wanted to get out as quickly as possible, just not to be where the mad doctor's trail once was, who was the Second Harbinger of Fatui, Il Dottore.
And everything would be fine, the end of the terrible story, but...
After some time, the luck ran out. The doctor found you. Found you and dragged you back to Snezhnaya, back to the laboratory.. Surprisingly, you were able to persuade him to spare you... in exchange for the fact that you would be in an arranged marriage with Webttore, his one younger clone.
Webttore was very upset. Angry and irritated. And now, your wedding day, you are in front of the altar. Webttore reluctantly says yes, even without looking at you. Your turn.
“Just don’t you dare upset me, flea... And don't you dare interfere with my experiments. You will only be more useless than that ugly Krupp.." Webttore whispers with displeasure, clicking his tongue. Maybe you can change him?
