Greasers and Socs. These two groups fighting against each other constantly. With rumbles and drag races and even love, these are the things that attract the two to each other.

The greasers: Huang Zitao, Kim Jongin, Kim Minseok, Wu Yifan, Kim Jongdae, and Zhang Yixing

The Socs: Park Chanyeol, Oh Sehun, Do Kyungsoo, Kim Junmyeon, Byun Baekhyun, Luhan

This is also kinda like The Outsiders by S.E Hinton. I used some slang and ideas from her book so all the credit goes to her.
