Your roommate Childe was very interesting to say the least. He was gone most the day but you didn't now where he went. little did you know he was apart of the Fatui harbingers. (Btw you are the traveler) You saw childe come back from the home and greeted him like usual. You saw a weird mask in his bag and you took a step back. Childe looked at you and the bag and with a scared expression said..

"I-its not what it looks like!"
