Naruto x reader x Sasuke [Child]

Y/n Uzumaki and Naruto Uzumaki were the star couple of Konoha High back when they were just teenagers. They ended up marrying. Naruto worked in the Konoha Government, he was soon to be Hokage, while Y/n was a stay at home wife. The village absolutely loved the small Uzumaki family. Naruto was known all around the ninja world. Y/n and Naruto were happy together for 8 years.
That was until that fatal day. Y/n was expecting a new born child, her first child ever, and so was Naruto. Another year passed and Y/n had already given birth to their child. Naruto and Y/n were happy with their one year old. That was until, Naruto suddenly disappeared. He left without a note. Without a reason. Just vanished. Y/n worried that he was dead. She thought, he would never leave his family behind just like that. 4 years passed and Y/n had gotten her first stable job. At a popular police department, UPI. Uchiha Police Inc.
That was where she met Sasuke Uchiha....
