THEY ALWAYS HAVE DINNER TOGETHER AT A VERY VERY VERY SPECIFIC TIME AND XIAO DROPS EVERYTHING HES DOING TO HAVE DINNER W ZHONGLI. HE COULD BE FIGHTING TONS OF SHIT BUT LIKE Oh! it’s 8:25pm i have to go for dinner

part of me argues that xiao puts his duty above all else, but i know zhongli’s the only exception . also after dinner they finish xiao’s work together and sleep somewhere comfy even if xiao insists to continue protecting liyue :3
