1. The Defendant shall pay to the Plaintiff KRW 21,472,935 and a rate of KRW 20% per annum from December 4, 2014 to the date of complete payment.

In full view of the facts without dispute between the parties, Gap evidence No. 1, and the purport of the whole pleadings, the plaintiff supplied steel products to the defendant at the defendant's request. As of December 31, 2013, the plaintiff supplied steel products to the defendant 8,470,168, and thereafter the plaintiff from January 2, 2014.

7. It is recognized that steel materials equivalent to KRW 47,543,337 were supplied to the defendant several times until July 30, 201, and the plaintiff was paid KRW 34,398,340 from March 10, 2014 to July 25, 2014. According to the above facts of recognition, the defendant is obligated to pay to the plaintiff damages for delay at a rate of 20% per annum as prescribed by the Act on Special Cases concerning the Promotion, etc. of Legal Proceedings from March 10, 2014 to July 25, 2014.

In regard to this, the defendant argued to the effect that since the price of steel materials supplied by the plaintiff was excessively high so high that it was caused by the closure of business from the customer, some of the price should be reduced. However, there is no evidence to acknowledge the above argument by the defendant, and the above argument by the defendant is without merit.

Therefore, the plaintiff's claim is reasonable, and it is so decided as per Disposition.
