"If I may ask, how is your home life, sir?
“Hm? I suppose the word for it would be comfortable.”

They've just been together for so long and they are just so perfect together, everything is comfortable

This is very normal, Zhongli will sit on the floor against the couch while he reads work things, Venti will play on his phone and keep insistent physical contact with his husband, maybe give Zhongli a massage when Venti notices him tensing up, while Zhongli will every so often just rest his head against Venti's thighs, sometimes just leans back into Venti and lets him play with his hair

The only place Zhongli actually dresses down and removes his gloves is at home with Venti
His hands and arms are completely tattooed and Venti loves them, Venti gets to kiss Zhongli's fingers, his tattoos, actually gets to roll up Zhongli's sleeves, no one else gets Zhongli not completely not dressed to the nines, sorry everyone else, just Venti

They're married, been married so long, been together so long, they just know each other so well and are so domestic and comfortable with each other
