Innocent Sorrow (D. Gray Man Fan-Fic)

What happens when a new exorcist arrives at the Black Order? This isn't new; they get new exorcists all the time. But this one's different. She's related to another exorcist, and is bound to fall in love with another. So the new question is, what happens when the newcomer starts to love the one person her own brother can't stand? Does he even love her back? And what will Kanda do to stop it all?
