IMO SasuSaku doesn’t work as a pairing.
SasuSaku isn't believable as a couple in my eyes. It just comes off as one-sided and unhealthy on Sakura's side. The girl is attached to Sasuke's hip and never doubts her feelings for him.
Not to say Sasuke wasn't nice to Sakura; he was:
- During the beginning of the Chunnin exams, he praised her for figuring out the genjutsu for the classroom
- In the forest of death, he protected her from Orochimaru after Naruto was unconscious
- Sasuke protects Sakura from the Sound Ninja but that doesn’t imply romance; it's just protecting a comrade in danger.
None of that's romantic, lets not forget:
- Naruto protected Sakura & Sasuke from Gaara
- Sasuke protected Naruto from Haku
- Naruto protected Sakura when she was about to be killed by Sasuke.
- Sakura protected Naruto from Zabuza's blade
Naruto, Sasuke & Sakura all protected each other because they were a team, and Naruto & Sasuke protected Sakura because she was the weakest member of Team 7.
Plus Naruto protected Sakura as well, so what makes Sasuke different than Naruto?
People will argue the scene when Sakura tries to stop Sasuke from leaving the village to join Orochimaru is romantic, but I disagree.
Sakura tries to explain to Sasuke that despite having friends and family, Sasuke leaving would be the same as being alone. What is Sakura's home life to justify her saying that? Is her home life that bad? How can you emphasize Sakura saying that when we don't even know her home life?
Sasuke then knocks her out, thanking her for everything and leaving her on a cold bench. I took this as Sasuke letting her off easily.
Now with the Samurai Bridge fight, people will argue that Sakura doubted her feelings for Sasuke when she tried to kill him but that's simply not true.
Not only did she fail in trying to kill him, she didn't protect Naruto. She was a damsel in distress once again in that fight.
She still thinks about Sasuke in the war arc and while fighting Madara Sakura says "Sasuke isn't concerned about me". Sakura still cares about Sasuke's opinion of her, does that sound like moving on or doubting her feelings to you?
