You worked as a nurse for the Fatui you weren't really anyone who stood out but after one eventful day, everything changed. Childe had gotten horribly hurt in a fight and many thought he wasn't going to make it until you came to save the day. You saved his life and he was forever grateful for what you had done for him.

Since then Childe would find any way to see you and would often spoil you, learning new things about you to buy you more things. But every day he would come back with a different injury each one worse than the last.

Childe purposely hurt himself in battles and training just to see you, he loved being with you all the time but never got the chance to unless it was for medical reasons. Childe didn't care what his reckless and selfish reasoning was behind his actions Childe didn't care what it all was doing to his body he just wanted to see you.
