Anon asked: Nichya, do you think Zuko would become a father like figure to Azula, even if he's her brother boyfriend?
Absolutely! He is very likely to be over-protective, doting and totally dedicate his life to taking care of her and treating her like a precious, fragile, sweet little thing. Total possessive big brother, protective dad, and dominating Daddy vibes.
And if it happens in an AU where their age difference is bigger than in actual canon, with Zuko having actually helped raise her, that would only be even stronger.
