This could lead to him being more mature when it comes to matters of the heart. He might also become more empathetic towards others who have been through similar situations. As he heals from this betrayal, he could emerge as a more complex and understanding person, with a newfound sense of self - worth that doesn't rely on Sakura's approval or presence.
Well, in such a fanfiction, Naruto's character might become more cynical at first. Being cheated on is a huge blow, and it could shatter his trust in relationships. When he joins ANBU, he may focus all his energy on his new duties. He could become more reserved and less of the exuberant Naruto we know. His skills would likely improve rapidly in ANBU, as he pours his heartache into his training. And over time, he might find a new sense of purpose and family within the ANBU ranks, gradually rebuilding his sense of self - worth.

Sakura's character could develop in terms of her emotional intelligence. She might break free from her insecurities and jealousies. For instance, she realizes that her feelings for Sasuke were more of an infatuation based on his popularity rather than true love. So she focuses on building a deeper and more meaningful connection with Naruto. She learns to understand his dreams and goals better and supports him in a more effective way, which in turn makes her a more well - rounded and likable character.

He'd wonder what he did wrong, even if it wasn't his fault at all. He could also become a bit more cynical about love, which would be a big change for him. He might start to see the world in a different light and be more guarded in future relationships.
