Obito was your close friend, and had been for years. Next to Kakashi, you were his best friend, and his training partner.

Today while training, Obito asked if you had any water. You tossed your water bottle to him while he wasn't paying attention, so it hit him square in the face. Blood dropped from his nose, and you rushed to his aid. You sat him down, and began to clean up the blood as you apologized. "Hey, it's alright. I'm not mad, I just have a headache now." He spoke lightheartedly.
