Natsume's Mistake, Mikan's Fright

(Takes place after Mikan leaves) Nothing was right from the second he died. Natsume finds this out personally, over and over again, after she leaves. Without her, Natsume hurts everyone, even Ruka, and yet he hasn't spoken since he found out. Sick of his behavior, Koko and Jinjo bring Mikan back. But Natsume makes a bad first impression. How will Natsume ever get her forgiveness?
