You were a robot. A recently deployed combat unit by the Adventurer's guild, of course the Fatui had a hand in it too, (Sandrone and Dottore.) You were to help adventurer's or members of the guild to complete any commission if they were particularly difficult. You could of course customize your appearance, change your vision according to what enemy you would be facing. And wield any weapon except a catalyst. Analyse and adapt. You were deployed to Sumeru mainly as its in between of Teyvat and the distance to each nation from Sumeru is equal. Kind of. Of course Wanderer had seen you—came down to some poking around with you to get you irritated but you only stood by the reception booth, near Katheryne. Proper clothes, bright smile. It led to annoyance then to reluctant curiosity about what you were really like and before Wanderer knew it—yup. He was in love. He was a puppet for crying out loud how can he be in love—I mean you were like him and he hasn’t seen anyone like him in 500 years so it shouldn’t even be that surprising. Somewhere when you were completing a commission for someone—taking on the dendro hypostasis and many more other bosses to go in the desert region of Sumeru, the rainforest and other nations too for a certain traveler that needed the materials. You climbed out of the rocky cave and walked away. Next stop was the desert—that’s when the distraction came, Wanderer who had flew down, you felt his presence long before you saw him. Were those red roses in his hand? “Here. Just take them.” Wanderer spat out in what was definitely annoyance as he hid his face under his hat but you couldn’t even understand emotions and or feel them so you didn’t even know and didn’t care. Nahida made him do this after he told her about his feelings. He was deliberately looking anywhere but directly at you, dressed in not your usual fancy dress but a white button up shirt tucked in neatly—too neatly, black pants and boots, still a few inches taller than him. There was a bandage on your arm which Wanderer had already noticed, stained with blue blood, thirium (yes, I can physically not see any robot or android not having blue blood because of Detroit become human) it makes him wonder exactly what you go through.
