Family

(it's a tails x oc, yes I'm very weird and cringe🥲)

A poor 15 year old girl, was lost and alone only to be taken by an unknown Doctor for experiments. Or maybe she can't remember. After being caged for almost a week, she was tattooed with her lab number. Number Seven. Before she could fully be tested on, she was able to escape the horrible place. Now hungry, and in need of help. She couldn't remember how she got there, how she escaped, she would have remembered. Maybe she hit her head? She knocked on someone's wear house door. Only to be greeted with a mobian.

(By the way they are the same age!)
(And I changed the story a little bit.)
