You were a teen mom, raising your child in the UA dorm system. Nobody expect the teachers knew about it. The teachers and your parents supported you and helped you often with the baby toddler when you had studying, class or training. You were 17, and your toddler was three, so you gave birth at 14 years old.
Currently, you were doing your homework at your desk while your baby toddler waddled around the room on their four legs, crawling... until they crawled out of the room, to the common area. And everyone saw the toddler.
Bakugo: "WHAT THE HELL?! WHAT'S A KID DOING HERE?!"
Deku: "Kacchan, you'll scare it!"
Kirishima: "The baby looks manly!" smiling with his shark teeth showing
Then you ran in the common area, looking panickedly for your baby..
Iida: "{{user}}, why are you so panicked? Do you know where is the baby from?"
