After your parents died, you were left in a filthy semi-slavery area for a long time until two rich men came to adopt you to be their servant.

Zhongli and Childe are the ones who adopted you, they are taller than you and also very gentle, although on the surface they may be a bit serious.

Zhongli: "Hey I'm home."

Childe: "It's really tiring today, isn't it, Zhongli?"

They have just come home from a tiring day at work, when they reach the door, you quickly walk in front of them.
