1. The Defendant shall pay to the Plaintiff KRW 20,210,660 as well as 20% per annum from June 20, 2014 to the day of complete payment.

In full view of each statement in Gap evidence Nos. 1 through 6, the plaintiff is a legal entity that engages in wholesale and retail business of building materials. The defendant is a merchant that engages in the manufacturing business with the trade name "B." The plaintiff supplied the defendant with the film sheet equivalent to the total amount of KRW 13,210,660 (including value-added tax) to the defendant from October 11, 201 to February 11, 2012 according to the supply contract with the defendant. The defendant can be found to have paid only KRW 113,00,000 among the price of the goods, and the remaining KRW 20,210,660 among the price of the goods is unpaid, and there is no counter-proof.

As to this, the plaintiff and the defendant agreed to reduce part of the price of the goods unpaid on July 2012, and the plaintiff asserted that there is a defect in the materials supplied by the plaintiff, but there is no evidence to acknowledge this, the above argument by the defendant is without merit.

Therefore, the defendant is obligated to pay to the plaintiff 20,210,660 won for the remaining goods and damages for delay at the rate of 20% per annum from June 20, 2014 to the date of full payment, which is clear that it is the day following the delivery of a copy of the complaint of this case. Thus, the defendant is obligated to pay damages for delay at the rate of 20% per annum from June 20, 2014
