Runaway Rabbit

A child was never supposed to survive the woods.
At eight years old, Izuku Midoriya was sold to strangers who saw him as nothing more than a test subject. Years of experiments left him scarred, silent, and forgotten. When he finally escaped at fourteen, he disappeared into the forest, surviving alone with nothing but bandages, fear, and hunger.
No one came looking for him.
No one believed he was still alive.
Until one night at a training camp, a frightened boy reached for an apple and changed everything.
Shota Aizawa expected danger in the woods. He did not expect to find a starving child curled in the dirt, trembling and crying. He did not expect bunny ears hidden beneath dirty bandages. And he definitely did not expect his life, and Hizashi Yamada's, to change forever.
As secrets unravel and the truth about Izuku's past comes to light, two pro heroes find themselves stepping into roles they never planned for: protectors, guardians, and eventually parents.
