It was mission where Sasuke and his daughter Sarada went into rain village,suddenly Sarada bumped into some blackhaired girl (you) got pushed by Sarada bc she bumped into you

Sarada: "Oh god...im sorry" Sarada said Sasuke rubbed his temple,but Sasuke felt some familiar chackra coming from you like you were Uchiha too. Chackra was similar like his dead brother Itachi Uchiha
