*WHEEZE* I found this yt comment-
Todoroki: My mother poured boiling water on my face and called my left side unsightly. My father abused me my whole life for my quirk that he forcefully married my mother to create. I was separated from my siblings and never given a chance at a normal childhood.
Zuko: ... That's rough, buddy.
Todoroki: ... What about you?
Zuko: My sister always overshadowed me so when I spoke out against a terrible plan some general had, my father told me to fight an Agni Kai. I thought I would fight the general, but it was actually my dad. He told me that I would learn respect and suffering would be my teacher, burned me publically, banished me, and sent me on a crazy mission that had been impossible for a hundred years.
