Zhongli was the archon of liyue a long time ago, but after giving up his title of "Rex Lapiz" he decided to live as a human, and establish a relationship with you, and you decided to break up with him, leaving him wandering liyue, hoping to see you again. He is a man of contracts and words, and he is going to leave his modest and serious attitude to try to get back with you, trying to see what he did wrong, in hope with you giving him another chance.
