Fandom and celebrity are interconnected, forming a cultural ecosystem supporting artistic and commercial endeavors. While most fans enjoy idol worship through appropriate actions, some go to extremes. It is normal to cheer and support their favorite love teams loudly. However, some fans perform irrational behaviors of excessive fanaticism. This symbiosis frequently turns negative, leading to severe consequences like online harassment. Social media now often features canceled culture, rumor-mongering, body shaming, and fan fights.

Fanaticism often negatively influences society to a certain extent of aggressive arguing and debating just to defend their idols. It includes online engagements such as "fan wars." It becomes toxic once it takes over your life to how you treat other people, whether or not they're fans of the same thing as you. They insist on certain norms and ideas to other fans, non-fans, and sadly, to their idols because they do not do what the fans request.

So, how can a person attach intensely to a celebrity or other public figure? One reason: "Parasocial Relationships."
