Teen Top and Infinite have been rival groups for 2 years now.....they have fought with all other previous gangs in Korea except each other as they both know how powerful they both are..But they too have rules to avoid the fights:

1. Both groups arent allowed to be in the same place at the same time

2. Both groups' members are allowed to be friends to reduce the chances of fights.

Last but he most important rule:

3. They can't steal each other's girl.

L.Joe and Myungsoo were friends actually pretend friends as both of them became friends to eavesdrop on the other one...however their fake friendship is crumbled with the entrance of something so pure and meaningful, something they never experienced LOVE !!!
