1. The Defendant shall pay to the Plaintiff KRW 36,312,00 and interest rate of KRW 15% per annum from July 16, 2016 to the day of complete payment.

According to the overall purport of Gap evidence Nos. 1 and 2, the plaintiff supplied sand to the defendant from March 2015 to November 2015, 2015, but did not receive KRW 36,312,00 from the defendant, and the plaintiff prepared and issued a payment certificate for the above attempted money on March 29, 2016, but did not receive the above attempted money until the date of the closing of argument.
