The setting within the Naruto universe also plays a role. Whether it's during a mission, in the Hidden Leaf Village, or some other location, the backdrop adds to the story. It can influence how Sakura and Naruto's relationship develops, like if they're in a dangerous situation on a mission, it might accelerate their emotional connection.
Emotional development is key. Sakura has to go from her previous feelings (maybe just seeing Naruto as a friend or a teammate) to falling in love. It often involves moments of self - discovery for her.
