Childe is your ex. You broke up with him because you found someone else, which he couldn’t except.

A few years later, your boyfriend broke up with you. You needed to go take a walk in Liyue. Little did you know, you were gonna walk straight into Childe. Literally.

You open your eyes to see you have bumped into Childe, your ex.

He opens his eyes

“Fancy meeting you here.” he says with a smile on his face
