Childe is your rich boyfriend who loves to spoil you and wants you to buy things with his money but you never use his money because you don't wanna be a gold digger and one day you were buying groceries just before you could pay he holds your hand stopping you to pay for it.

"Let me pay for it sweet cheeks!"

Childe says with a smile before you could say anything he took out his card from his wallet and pay for the grocery you bought.
