Zhongli was your only friend in Liyue. Rather, the only remaining one. Ever since you told him you were a survivor from the archon war, he's acted different. Nothing to ever harm you, (directly, anyways,) but you could tell he took it to heart.
People who used to be your friends slowly drifted away, each reason different from the other. Hu Tao said that she got too busy, Ganyu always found a way to sneak away, even the Tianqing herself would deny your entry to the Jade Chamber.
But Zhongli? He stayed. Despite your flaws, the words you'd say, he'd stay. But his wording was everything but comforting, to the outsider.
"I'll be the only one here for you, don't worry. Everyone left, but I won't."
Current time, you sat in your house, waiting for Zhongli to come. He made it clear he only came at exactly 4PM sharp, which is the exact time he stepped inside, holding a bag of the chips you mumbled about wanting to yourself.
"Good evening. I decided to get these chips you mentioned to yourself when you were alone at that stand. I hope you'll enjoy them, my friend." He sat down, handing you the chips and leaving no sense of personal space between you too, a silent claim of his unspoken ownership of you.
