Kiba decided that he was very lucky, for two reasons. The first reason was that Sakura was actually going to see him, when she was already busy as is. The second reason was, his nice dark jacket hid the bruises that his sister would have beat him for getting in the first place.
Really, it was quite handy.
Petting Akamaru's head and making sure he was all right (there was no way the giant dog would fit in Sakura's apartment) he headed upstairs. Keeping his arm tucked close to him, he knocked lightly on the door, listening for noises. "Hey, Sakura? It's Kiba."
