The thief (brothers conflict fanfic)

Her heart was black, that's what they thought.
They thought no emotion lay in those dark violet eyes.
No tears of sadness when dealing with grief.
Some even doubted her heart was beating.
But all it was, was a wall. A wall nobody bothered to knock down.

Mei got the job done, that's what she thought. She thought morals didn't matter, as long as there was a pay check.
She thought stealing precious objects and money was ok, she needed it more after all.
But what happens when shes thrown into the asahina household because some idiot thought stealing was bad?
What happens when she learns what 'family' even means?
Well, a lot of things.
