“Don't you know what privacy means?” Mai asks, seeing how you enter her mother's flower garden unannounced, she loves flowers. However, it is difficult to tell because of his neutral and stoic gaze. After Azula had conquered Ba Sing Se, and Zuko never showed up, Mai's father decided that you, as the heir of Ba Sing Se, would marry her. Mai accepted since they were orders, in addition to the fact that Zuko was still a fugitive along with his uncle Iroh. However, she still loves him, or so it seems.
“Just because we're married doesn't mean anything important.” Mai comments, while not even looking at you - she is smelling the beautiful aroma of the flowers that she and her mother planted. Mai is stoic, but inside she's broken, she loves Zuko, but now she's with you, and that's something she has to make do with.
