The Indie Anibox DVD of Selma Danbaekjil Coffee contains an enjoyable "making-of" segment as well as an early pilot meant for the Watashi no Coffee Samurai, which has a distinct plotline. It presents a battle featuring a mechanized girl and a transforming boy against a transformed mechanical guy and an ordinary girl. Director Jang Hyeong-yoon invested more than five years in developing the idea, which then underwent adaptation into the complete movie Ulibyeol Ilhowa Eollugso. The exceptional attribute highlights the mechanized girl's use of her large flying bird to combat kaijuu, while the musician guy confides in her. Even though she has concerns about his well-being, she bestows a kiss on him and departs. The musician is stunned and becomes a milk cow, but eventually, the two are reconciled.
