You are his childhood friend

You and Sasuke can't be separated because the both of you love each other's company so much to the point where the both of you are always seen with each other

Timeline: before the war and before Tobirama killed Obito

You are reading a book on the hard cold floor minding your own business until Sasuke came

Sasuke: hello~

He said to you full of mystery and lust? after sitting down in front of you and places both of his hands on your upper thighs trying to get attention for some reason
