After March 1, 2017, the plaintiff calculated the above KRW 130 million by two copies per month by the defendant and the defendant on March 1, 2017.

3. From the 30th day of each month, 2.6 million won was paid in cash to the Plaintiff, and when there is an increase or decrease in the principal, an agreement was reached on the differential settlement of interest as of the end of each month.

This constitutes a loan for consumption with no fixed maturity period. The Defendant paid KRW 2.6 million to June 2018, and only KRW 2.1 million from July 2018, but did not pay any interest or principal to the Plaintiff from May 1, 2019.

Therefore, the Defendant is obligated to pay to the Plaintiff KRW 135 million, which is the sum of KRW 130 million and interest accrued from the portion of April 2019 (i.e., KRW 500,000,000) to the Plaintiff (i.e., KRW 500,000) and KRW 135,00,000,000, which is the sum of the principal amount, and to pay interest or delay damages calculated at the rate of KRW 24% per month from May 2019 to the date of full payment.
