The plaintiff processed and supplied the above original unit to the defendants around August 31, 2016. The defendant Eul around that time, and until September 30, 2016, paid the plaintiff KRW 6,391,616 (including value-added tax) to the plaintiff, and the defendant Eul requested the plaintiff to pay a copy of the complaint of this case 1-2,500 won to the plaintiff from the head office of this case to October 15, 2016, the plaintiff can jointly and severally seek delivery of the complaint of this case 16-1,570% of the total complaint of this case to the plaintiff.
