Seo-yeon (OC) is the average girl you find in class, with average looks and average grades. She doesn't find anything nice about kpop idols and thinks that kpop is overrated. When the news of BigBang members transferring into Seoul High School spread, the girls in her class has practically gone crazy and would probably die just looking at the members, but Seo-yeon doesn't care less. She thought her high school life would be simple and uneventful and BigBang would not intervene into her life.
