The brilliant thing about Naruto 619 is Kishimoto basically explained to his reader what’s the deal with the Uchiha clan and the mechanism of the manifestation of the Sharingan. By doing so, he basically highlighted that it all stems from the Uchihas LOVING too much and their grief in the inability to hold on to those they love the most.
Without admitting to anything, Sasuke is confirmed in canon to possess a strong love for Naruto. Whether that is platonic or romantic is probably a moot point because the fact remains: Sasuke loves Naruto strongly that his Sharingan awoke/evolved in Naruto’s presence. That’s just a perfect roundabout way of saying that Sasuke has deep feelings for Naruto that he doesn’t hold for anyone else bar Itachi. And for that? You got to give Kishimoto props for one-upping everyone.
