The charming and handsome Do Kyungsoo is quickly accepted by his new school's biggest A-list clique, The Fabs. He begins to adjust somewhat well until he accidentally falls for Kai, the ex of current Fab leader, Byun Baekhyun.

The Fabs (before Kyungsoo) consists of 3 members. Byun Baekhyun the leader, Oh Sehun the self-conscious, and Luhan the clueless. Together they make EXO High School's most well known and notorious clique. 

Disclaimer: Obviously the main part of the story line comes from the movie "Mean Girls" and I don't own the EXO members.
