Another plotline could be that Sakura makes a decision that deeply affects Naruto's life in a negative way. Maybe she chooses to side with an enemy against Naruto's wishes, and this betrayal makes Naruto feel so hopeless that he becomes depressed. In these fanfictions, the writers often explore the complex relationships between the characters and how their actions can have far - reaching emotional consequences on others. There's also a possibility that Sakura's actions cause Naruto to lose his dream or his sense of purpose, pushing him into a depressive state as he feels lost without that driving force in his life.
One common theme is isolation. When Naruto gets depressed, he often isolates himself from his friends and the village. He feels like no one can understand his pain.

A common plotline is Sasuke's struggle with self - worth. Since he's often driven by revenge and a sense of inadequacy compared to his brother, in fanfiction, this can lead to a downward spiral of depression. He may feel like he's not living up to his potential or the expectations of those who have sacrificed for him.
One possible plotline could be Naruto's initial shock and disbelief. He might go through a period of self - doubt, wondering what he did wrong. Another could be his journey to find himself again after such a betrayal. He might focus on his ninja training more intensely to distract himself from the pain.
Loneliness can also be a theme. She may feel isolated in her depression, like no one truly understands what she's going through. This could be because she's hiding her feelings or because others are too preoccupied to notice.
One possible reason could be unrequited love. If in the fanfiction, Sakura continuously rejects Naruto or shows no interest in him, it can lead to his depression. Naruto has deep feelings for Sakura for a long time, and constant rejection can be soul - crushing.
Another plot could involve jealousy. If Sakura becomes jealous of Naruto's growing popularity and power among the villagers, she might betray him. She could spread false rumors about him, which would lead to the villagers turning against Naruto.
One common theme is self - growth. Naruto has to learn to be independent and focus on himself instead of pining after Sakura. Another theme is friendship. His friends support him through this difficult time of getting over his feelings. For instance, they might take him on adventures or just be there to listen.
It shows his vulnerability. Usually, Naruto is seen as a strong and determined character. But in this fanfiction, his depression over Sakura reveals that he has a soft side, especially when it comes to love. This adds a new layer to his character.
A common plotline is Naruto getting hurt during a mission. Sasuke then blames himself if he wasn't there to protect Naruto. He might vow to become stronger so that he can always be by Naruto's side in future missions. Another is when Naruto is hurt by an enemy who specifically targets him because of his status as a Jinchuriki. Sasuke will then go on a revenge spree to take down the enemy.
