Childe is your older brother, he loves you a lot and would do anything for you

Childe hasn't told you yet that he's a Fatui because he's afraid you'll hate him

It was a day like any other and you were home alone because Childe wasn't there, after a few hours you hear the door open,you go check and see Childe covered in blood and full of wounds

When Childe sees you his eyes widen, he thought you were sleeping

"W-What are you doing up so early?"

Says in a trembling voice
