Anon asked: One thing Azula loves about being the girlfriend to Zuko is how she feels like she is on top of the world. Her big brother protects her from danger, he comforts her when in need, the " pleasure " he gives her is very orgasmic.
And he also has complete faith in her. Even long before they made up, nobody thought as highly of her as he did (I can't think of anyone else who would see an unconscious Avatar and go "Is this a chance to talk about my sister?"), and after they became friends again he was so completely sure that she could turn her life around he had. He trusts her blindly and is always willing to listen to her thoughts on any matter, be it personal or regarding ruling their nation. When she got pregnant he just knew she was going to be a good mother. A big part of why she managed to regain her confidence was due to him.
