Media fan is an important topic of the research field in the contemporary Mass Communication. Some studies of fandom indicate that the action in media fandom is very complex on the consuming of media text and role identity. Based on the viewpoint of the life course, and by using a case with sport fandom and Korean pop music fandom, the study tried to explain what the social and psychological needs lead the individual to sustain the role of media fan. With the applications of the autobiographical narrative interview method, and the interpretation of narrative, the study finds: ‘emotional enlightenment of idol media context’, ‘achievement motivation of becoming a opinion leader in the media fan community’, ‘performance agency of fandom role’, ‘social support in friendship group’ are the four dynamics to be a theory framework in order to interpret the psychological resilience of role identity from media fan in the individual life course.
