I like it because is sweet, cheerful and is based on confidence and support on each other.
Being honest I started as a SS shipper (even then I disliked Hinata, so I didn't ship Naruto with anybody) I couldn't tell if Naruto's feeling were real love or just a crush, so NS didn't come to my mind. Then Sasuke left and I had a heartache by looking at the blonde being so sad for not being able to accomplish the promise he made to Sakura (it just broke my heart)
I truly came to love NS to the extent (not kidding) that I can clearly feel the future tears of joy if they end up together.
