Sarada was so blushy, and Naruto was just being himself...It's like she wants to be his daughter now, and Boruto is gonna like Sasuke as a dad because Sasuke is more edgy and cool.
Not surprised though, Sasuke wanted Naruto, his brother liked Naruto and trusted him to take care of his brother, and now Sasuke's daughter admires him. The Uchiha just crave that Uzumaki.
