Dragons are born in twins set, one dominant while the other is submissive. 
One can't survive without the other, the dominants are sent to military schools, they'll spend most of their life-controlling their Dragon side.
While the other half goes to Dragon Academy, they'll learn how to cope with being submissive, they are categorized into littles, pets, or simply submissive. 
The older dominant would meet them there, teach them how to shift, protect them from all dangers, and finally claim them as theirs forever. 
Kaiden is a special case, a little who never regressed before, she also never cried, until crossing roads with Adrian, a fiery red dragon.

Dragon Academy

I don’t feel well at all, I woke up with a stomach ache, I’m too hot but daddy had so many layers on me, I tried to push the onesie off me, but it’s up to my neck and I can’t reach the zipper, I also had a blanket covering me. I started to whine, kicking both my feet trying to get it off me, daddy must have woken up with my whining and crying, he got up rubbing his eyes, and getting me out of the crib.

/"What's wrong princess?/" he asks, while I just cry and kick. Daddy takes my onesie off me, finally letting me breathe, next he took the diaper off too, now I'm really better, he got a baby wipe cleaning me, I loved the cold feeling on my burning body.

/"Is that it, my princess? You needed a change/" daddy coos at me, before setting another diaper on me, that when the cries and screams started again, it's too warm, I don't want it.
