The Plaintiff supplied the Defendant with civil engineering materials equivalent to KRW 108,835,100 at D from October 2019 to November 2019, but the Defendant did not pay KRW 48,835,100 to the remainder of the price of the goods.

(2) The defendant is obligated to pay to the plaintiff 48,835,100 won due to unpaid goods and delay damages at the rate of 12% per annum from February 29, 2020 to the day of full payment, which is the day following the delivery of the payment order in this case, to the day of full payment.

3. The defendant's argument as to the defendant's assertion argues to the purport that the defendant's claim for the price of the goods is unjust even though the defendant promised to pay the price of the goods in this case to the plaintiff by March 31, 2020.

On the other hand, it is insufficient to recognize that the plaintiff suspended the payment date of the above goods only with the materials asserted and submitted by the defendant, and there is a lack of other supporting materials (only there are the defendant's expression of intent and the name and seal of the defendant to pay the money at any time by the defendant on March 5, 2020, and there is no content that the plaintiff would postpone the payment date or the name and seal of the plaintiff's side). The defendant's assertion is rejected.

4. The conclusion is that the plaintiff's claim is reasonable, and it is so decided as per Disposition.
