Lily(OC) is a trainee for a famous Choreographer who's tells YG to come take a look at her. Lily impressed YG enough for him to sign a contract with her but one part of the contract she had put in there is that she is to be put in a male group. 

Bobby and the rest of the guys first meet Lily in the practice room while she was showing YG her own dance to one of iKon songs. As they watched her they were in awe of the movements of her dance moves. As Lily's time at YG continues she does music videos with G-Dragon and Masta Wu and other top names she also does a music video with iKon and as she does the video with them her and Bobby grow a friendship that may turn into something more. 

This is going to be one story that will have guest staring groups but iKon is the main group.
