Childe was in love with Zhongli, more precisely, he was obssessed with him. He couldn't stop thinking about him or get jalous whenever someone else than him would made the archon laugh or even smile.
The god didn't really saw it but now he could clearly see it because the harbinger was actually pushing him against a wall, a possessive and predatory look in his eyes. The fatui was so close that he could feel his breath against his skin.
"I can't stand that anymore, Zhongli. I don't want other people to look at you like that, it annoys me so much and you don't know how much I retain myself from hurting them... Look at me and only me." the ginger said as he moved a hand on Zhongli's chin to make him look up at him. Childe's voice sounded like he was angry but loving at the same time.
