I saw the "100 Otp questions" by the-moon-dust-writings on Tumblr, and I wanted to answer all of them.
1. Who loves flower crowns more?
Most of the time, neither of them like them very much, but Zuko likes seeing Azula wearing them, especially because of the cute, somewhat embarassed face she has to put them on (usually because Kiyi begged her to). His sweet smile when he looks at her makes her not hate them that much.
2. Who is the one who likes to cuddle?
Both. These kids are touch-starved.
3. Who has awful taste in music?
My money is on Zuko.
4. Who is the meme lover?
Azula. She's constantly making jokes in the show, so I feel like she'd like them. She particularly likes the ones that annoy Zuko.
5. How did their second date go?
They probably had dinner somewhere quiet, surrounder by candles and flowers, talked and teased each other, had dessert and a few drinks, then fucked on the table.
6. How many children do they want/have?
3-5.
7. Who hides the weapons?
Both.
8. Who is the better dancer?
Zuko.
9. Do/Did they have a theme wedding?
Yes, it was Game Of Thrones. No.
10. What do their parents think of them dating?
*giggles* Ozai is disappointed in Azula, and surprised that Zuko managed to "drag her down to his level". Ursa and Iroh both freaked out and were against it at first, but eventually learned to live with it.
11. Are they a super sappy couple?
100% yes.
12. How did they get together?
Zuko helped her recover after her breakdown, and they both because closer than ever, spending as much together as possible, and were insanely protective of each other. It was only a matter of time for them to hook up.
13. Who asked the other to get married?
Azula sort of decided they'd get married eventually shortly after they got together, and was already making plans. Zuko still had to buy a ring and pop up the question to make their engagement official, and was very nervous even though he knew she'd say yes.
14. Who stays up too late and makes stupid jokes?
Zuko.
15. Who is the nerd?
Azula.
16. Who knows the most obscure facts?
Depends on what you mean by obscure. Useless curiosities? Zuko. Historical shit? Azula.
17. Who makes the other a flower crown?
Azula. If she has to wear one to please both him, their kids, and Kiyi, then she's making him wear one too.
18. Who likes to read?
Both, but Azula likes it a little more.
19. Who bothers the other person while the other person reads?
Azula, because she's his little sister and she has the right to annoy him.
20. Who tutors the other?
Azula.
21. Do they have similar taste in movies?
Absolutely.
22. How do their personalities compliment each other?
Azula helps Zuko not letting his emotions get the best of him, while he helps her not be afraid to feel.
23. How do they tell everyone that they are going to be having a kid/adopting a child soon?
Either Zuko is making a sweet, yet formal speech during a especial dinner with friends and family, or Azula is making an inappropriate joke about how her brother is so insatiable that already got pregnant.
24. Who has better fashion sense?
They're Fire Nation, having great style is in their DNA.
25. Who will punch someone out if they are rude to their partner?
Zuko will beat the shit out of anyone who mistreats his sister. Azula will carefully plan revenge against anyone who doesn't treat Zuko like he is the greatest person in the world.
