A short love story that is inspired by the song, "Gap", sung by Ken (Vixx) and Hani (EXID) and the song, "I Don't Want to be an Idol", written by Ken (Vixx) and sung by him and Leo (Vixx).

Hani and Jae-hwan had been close friends since middle school. They were always together but never crossed the line. It seemed that there's always a gap between them.

Are they able to cross that line and close the gap between them?

Will they face any obstacles?
