But the hand landed on his head. And he didn't know what to do about that. So he remained very still, barely breathing, afraid if he moved the man might actually try and hurt him. And while he didn't care if he got hurt, he'd heal, he knew Madoka would hate it.

"Okay..." He said softly, not bothering to argue.
