It could cause a rift among the characters. Some might think he's being selfish by secluding himself, while others might understand his need for privacy. This difference in opinion can create tension and arguments within the group. Also, if Percy has an important role in the group, his absence could make it difficult for the group to function properly in certain situations.
Well, for his friends, his self - seclusion can be really distressing. They may feel abandoned and start to question their relationship with Percy. On the other hand, for his enemies, it could be seen as a sign of weakness or an opportunity to strike. They might take advantage of his isolation to plan an attack or spread false rumors about him, which could further complicate the situation when he eventually comes out of seclusion.

When Percy joins Kronos in the fanfiction, it affects the other characters in many ways. Chiron, the centaur mentor, would be deeply disappointed. He had so much hope for Percy. The minor demigods who looked up to Percy would be lost. They might lose faith in the idea of being a hero. The relationships that Percy had built over the years would be shattered. His joining Kronos would also make the enemy stronger, which would put more pressure on the remaining good characters to come up with a plan to stop them both.

For his friends, it could be a huge blow. They might feel abandoned and worried about his safety. For example, Annabeth could be extremely distraught, constantly worried about Percy's well - being.

His friends would be extremely worried. Sakura, for instance, would likely try to use her medical skills to help him and also try to figure out why he's doing it.

Sasuke might see Naruto's self - harm as a sign of weakness or, on the other hand, it could make him more empathetic towards Naruto as he has his own inner demons.
It can limit Percy's growth as a character. If Artemis is always protecting him, he might not get to face challenges on his own and develop fully. Other characters might feel sidelined because Artemis is so focused on Percy. For example, some of Percy's friends who also want to help him might find it hard to get involved if Artemis is constantly stepping in.
