Sakura expressing betrayel when seeing Narusasu gives me life, its so canon. She and Naruto are friends, but she always persued Sasuke and even fought with her childhood friend Ino over him, while Naruto claimed to hate him and was thus allowed trust. To find out he swept him up right under her. Ah, what a satisfying reaction. Too bad we didnt see the extent of Naruto's obsession or the extent of Sasuke's inner conflicts. And ofc the kisses. Some ships never die, thank god.
