This paper aims to explore the identity construction done by Indonesian moslem youth through fanfiction in her blog, tunshorin.blogspot.com. She usually writes about a love life of her Korean Idol who are not a couple in real life. However, she is kind of have the liberty to write Yong JunHyung, a member of Korean Boy band-Highlight-as the hero. She use him as a main character in her fan fic,titled Marry an Idol. A fanfic that has 16 episodes, starting from episode 1 back in 2010 and finish in episode 16 in 2018. She use the fan fiction as the media to fulfill her imagination about how a love story supposed to be.This study employ in depth t interview in order to gain a comprehensive answer. I analyze this problem by using the globalization theory from Appadurai who argue that media scape play an increasingly influential role in the possible identities and lives that individual imagine for themselves. The finding of the research shows that the writer of this fan fiction combine her real life identity as a moslem youth with this online identity, as a fanfic writer based on her Korean idol whom she is identified.
