In some fanfictions, Naruto might initially withdraw into himself. He could focus more on his training to distract from the pain. For example, he might go on long solo missions or intense training sessions in the woods, away from the reminders of Sakura.
Naruto could also become withdrawn for a while. He might isolate himself from his friends and spend time alone, reflecting on what went wrong and trying to heal his broken heart on his own. During this time, he might also start to question his self - worth.
In the fanfiction, Sakura could initially go into a state of denial. She may keep reaching out to her friends, trying to re - establish the connection. However, as time passes and she realizes it's futile, she might gradually become more independent. She could start making new friends who truly appreciate her, which helps her heal from the pain of being abandoned by her old friends.
Naruto may also try to find solutions. Despite the heartbreak, his optimistic nature might still shine through a bit. He could start to search for ways to mend the relationship with his parents, whether it's through magic in the Naruto world or by trying to prove his worth to them.
It can make him more introspective. He might start to question his self - worth. Since Sakura's rejection hits him hard, he could look inward to figure out what's wrong with him or why he isn't good enough for her.
He could see them as badges of honor. Naruto has always been a character who doesn't shy away from a fight. So, he might embrace the scars as proof of his battles and growth. He would show them off as a sign that he has overcome difficulties.
If Sakura were to give Naruto a token made of sakura leaves as a symbol of their friendship, and then later break off all contact with him and leave the village, Naruto would be heartbroken every time he saw a sakura leaf. The once - positive association would become a painful reminder.
One common theme could be unrequited love. Naruto has strong feelings for Sakura, but she may be in love with someone else, like Sasuke. This can lead to Naruto feeling heartbroken as he sees her pine for Sasuke and not return his affections.
She might be confused at first. Sakura is used to Naruto being friendly and always there for her, so his coldness would be unexpected. She may start to question what she has done wrong.
Naruto might initially feel sad and confused. He could try to prove himself to his friends by working hard on his ninja skills. For example, he might train extra hours to show his friends that he is worthy of their attention.
In many fanfictions, Naruto might use his ninja skills. He could suddenly appear and physically stop the bullies. For example, he might use his Shadow Clone Jutsu to surround the bullies and intimidate them into leaving Sakura alone.
