In those quiet moments with no advisors, or chaperones, or even friends present, they didn't have to be Fire Lord Zuko and Master Katara. They could just be Zuko and Katara, how it was meant to be.
Fire Nation nobility are quite particular about their hair. Such coveted locks are not to be touched by anyone, much less the peasantry. Zuko doesn't let anyone touch him at all for fear of being burned. Katara is Zuko's exception to both of these conventions.
