[But Rin being Rin, she thinks that tone is directed at her. She winces visibly, but takes the invitation rather than chickening out and coming up with some excuse to be anywhere but here. Her momentary panic makes her miss that Kaoru was saying she wasn't the only one needing to apologize, though.

Slipping in, she closes the door behind her, and immediately bows low, as if Shiro were behind her shoving her head down to give a properly humble apology.

It wasn't like her at all, but Kaoru was one of the few she had made friends with that was left from the relative beginning of everything. He meant a lot to her, and regardless of his behavior, she felt she had wronged him and that needed to be fixed.]

I'm sorry for what I said! You didn't deserve that after what happened to your brother! That's not how friends should act and I won't say anythin' like that ever again!
