When Kim Minhee discovers her elder brother, Minseok, has joined a gang called EXO, she immediately freaks out. After all, they’ve promised not to keep secrets from each other and Minseok broke that pact. Besides, a class valedictorian with a brother in a gang is unseemly-right? Minhee tries to get him out of the gang, but to no avail. However, she does manage to attract the attention of two of the gang members, a certain cocky Dragon and a mischief-making Phoenix....

Mianhe for my crappy description! The story is TONS better, I promise! ^^;
