Sakura, like Naruto, was one of the few to still want to save Sasuke. She held him down when everyone gave up on him and really the only one at home that could accept his love. Someone could argue Karin but their bond isn’t the same. Kishi isn’t the best with romance but i’m sure there was time off screen eos for Sakura and Sasuke’s love to blossom now that Sasuke isn’t running from everything anymore.
