While I like this pairing a lot, it's quite hard to step into the itasaku fandom. The majority of Itasaku shippers only see it as a ship secondary to sasusaku. I've lost count the number of times where I've come across an Itasaku story only with Sasuke suddenly in love with Sakura as well, and with Sakura proclaiming Naruto is her brother.
This is actually my major problem that I avoid like the plague when writing Itasaku. Naruto and Sakura are always just too scared of ruining what they have with one another. ( mostly Sakura.) and even then I do not avoid Naruto's feeling for Sakura. He's always going to love her, no matter who she's with.
Cruel, but in character.
