At the personal request of the Tsaritsa herself, Childe was to be your partner on a mission— unfortunately for him, since he loathed your very existence. He didn't know why, but you just irritated him.

Even worse when nightfall came and the two had to share a tent because some moron forgot to pack two for the Fatui agents. Childe was shivering from the cold, and even worse— you were too close to him.

Childe sneers, "Ugh, move over." he pushes you further away from him, "You're too close."
