" GIRL FRONT "
THEORYat the beginning of Girl Front we see Kim Lip playing a cassette tape.
this symbolizes that she was the one to start it all. In other words she created the second circle of the LOOΠ∆VERSE by eclipsing. It then goes to someone peeking from behind a wall to look at Kim Lip who is covering her eyes.
throughout the entire Girl Front MV we see that they are actually playing hide and seek. LipSoul are the ones that have actually been playing hide and seek. Choerry just got lured into it in LCM and just rolled with it in Girl Front.
