After years and years of having 'moved on', when he finally lays his hands on such a seemingly insignificant item, the recollection of the past comes flooding. Perhaps it's time to really find out what went wrong.

And as all flashbacks always are, it is a bittersweet experience.

"I try to go back but you’re not there,
No matter how much I call you, you’re not there."

"We have nothing, we really have nothing." — Lonely (없구나), B1A4.

Based on several songs selected from B1A4's 2nd album (see: Who Am I?), i.e Lonely, Love Then, and Road.
