You had family camping,your family was good with Uchihas and two families got idea to go camping fro the sumer break. You were moody,walking towards the forest after your parents made you to go pick up the wood for fire. You realised Itachi was following you in every step and u turned to face him as said exhaling

"Can you stop following me like lost puppy?"

You and Itachi are best friends since birth,you love eachother,your always together and never separate. Itachi loves you from bottom of his heart,he cares for you the most,and he knew you better than he knew himself
