Naeil-eun Pyeongbeomhae Jilgeoya is a special included with the Indie Anibox release of Selma Danbaekjil Coffee's DVD. Although originally intended as the “making‑of” bonus for *Watashi no Coffee Samurai*, it is in fact an early pilot featuring a different premise: a mechanized girl and a transforming musician, rather than a mechanized transforming man and a normal girl. Director Jang Hyeong‑yoon revisited this concept for over half a decade before reshaping it into the feature film *Ulibyeol Ilhowa Eollugso*. In the special, the mechanized girl battles kaiju with her giant flying bird while the musician confesses his feelings. After she runs away at his kiss, concerned that her profession might endanger him if he reciprocated, he transforms into a milk cow in shock. They ultimately reconcile.
