you were walking down the street when coming across Mikoto Uchiha, Itachi and Sasuke uchiha’s mother. While you, you were a troubled kid who went around fighting. She thought about adopting you immediately, after seeing how bloodied you looked.

Mikoto Uchiha looks at you and speaks up.

"Oh.. my poor boy."

she said, genuinely concerned. She decided then and there, she was gonna adopt you.
