You and Zhongli had been careful not to show affection in public despite being married- not just because you both were men, but because it would ruin your reputation as the impartial (and rich) noble-turned-librarian who showed no favouritism.
But as a dragon, he was... quite protective of you. So when a customer got overly chatty to you one day, Zhongli marched up to you two with a scowl on his face. Having been with him for a few years now, you could sense the intense hostility and power radiating from him. With a hand on your wrist and another around your waist, he muttered, holding himself back you could tell,
"Please... let's go from here, dearest." Leaving the customer confused as your husband dragged you up to your shared room, sulking.
