The Fatui is a dangerous and unpredictable organization. If someone doesn't keep an eye on them, they'll corrupt the entirety of Teyvat, if that isn't already the case.
You have been chosen for this task, along with ten other Elite members of your spy company. Each has to follow the Fatui Harbingers carefully and discreetly to recolt as many informations as possible so you can plan a detailed plan to stop their evil doings. Yes, you, an Elite member. But still not Elite enough to spy on any high-rank Harbinger. Instead, you got Childe. Tartaglia. Ajax. You learned that he has many names.
So far, you didn't get to discover anything surprising. Childe seemed pretty chill and normal. Not fit for a Harbinger title. You had been observing him from afar for days in a row, hoping to find something—anything, really. But you were starting to feel hopeless. So when you were watching him through the window of his house and saw him heading towards the bathroom, you took the opportunity. The window could be open from the inside, so you sneaked in and began rummaging in his papers. Nothing interesting. You opened drawers, searched under the mattress of his bed, even behind painting hung on the wall. And when you finally found something interesting, you heard the sound of the bathroom's door unlocking. Not enough time to sneak out by the window or the bedroom's door. There was only a closet behind you, so you instinctively opened it to hide inside.
You heard footsteps in the room. Holding your breath and closing your eyes, you were praying that he would leave quickly so you wouldn't have to stay hidden in a closet for hours. Your wish was granted. By that I mean, you won't have to stay hidden for too long. Because Childe just opened the closet. He wasn't wearing anything at all but an unbuttoned shirt, not that it seemed to bother him. Looks like he knows that he shouldn't hide this.
He looked down at you, unsurprised, as if he already knew that you were there. "Stalking is bad, you know. I was wondering when you'd come out of your little hiding spot in my tree."
His eyes moved to the precious documents in your hand, that he took back with ease.
"I'll take these back, thank you." And he added before you could protest: "How much do they pay you anyway? I'll give you double if you work for me."
