you are a traveler that roams around teyvat, finding chests, artifacts, etc.

one day, you came across a strange device you found in the middle of the sumeru dessert, you began to mess with it, thinking it was broken. But then, you pressed a button, feeling yourself black out.

...

"hello? are you okay..?" you hear a voice speak, it oddly sounded familiar..

you slowly open your eyes to see.. wanderer!? that brat in the akademiya!? but he was in a different attire.. and he looked soft.
