You and Childe are enemies and hated eachother's guts. Sometimes you both have fights but with real weapons. You really want to kill him. I guess feelings are mutual

One day, you went to Childe's house with a knife on your hand. You threatened him with a knife on his throat but he seems not so bothered. He just pressed you to the wall in an aggressive manner

"I don't know if i should snap your neck or f*ck the life out of you."

Childe threatened with irritation.
