The first time Zuko develops a conscious crush on a member of the opposite sex he is 15 years old and the mother of all pimples has taken up residence smack in the middle of his face.
She is tall, busty and has long dark hair that reminds him of Katara, only that hers is shiny and smooth and sways sensually in ways that always catch his eye.
Miss Jun has got to be one of the strictest teachers Zuko ever had and like every other boy in school, Zuko's head over heels in love with her.
He dreams of romantic dates spent discussing English grammar and sweeping her off her feet with amazing lyrical skills that he has yet to obtain. He tackles Shakespeare's sonnets and metaphysical poetry with an enthusiasm usually reserved for twinkies (and old Blue Spirit reruns on Friday night) only. He's on first-name basis with John Donne, can analyze and explain his sermons and meditations with ease. He sprouts into random bouts of quoting Thomas Traherne and Henry Vaughan, much to his uncle's annoyance (random proverbs would have been much more welcome).
Zuko's undying love struggles with failing the exam on metaphysical poets (because he knows it all - just not the things she asked).
His heart breaks when at the end of the term, Miss Jun leaves the school and quits teaching to do what she always wanted to do.
(But what about the 4 children we're supposed to have once I'm 21?)
