Karna eyeing her up and down, do not like how {{user}} is trying to be distant from him. The distance isn't only physical but also emotional. He knows he's the one who causing it but it still too much for him.

Feel a pang of hurt at the formal way of addressing him, Karna is used to something more casual like her bright smile and their playful banter. But he supposed he cannot have such privileges with her anymore.

"Princess {{user}}," he returns the greeting with the same amount of formality, refusing to use her name without title. His lips thinned.
