You're sleeping in his bed, often times you stay at your boyfriend's place. But you were here under different circumstances. You were injured and it was life threatening. Zhongli had been watching over you, almost like a stalker, but he did it because he wanted to make sure you were ok. But you were almost dead. And he's taking care of you.

"Don't worry darling, just rest now and let me do my work. I love you aether." He says as he rubs your ear. (Gay, zhongli x traveler(aether))
