1. The Defendant shall pay to the Plaintiff KRW 21,00,000 and the interest rate of KRW 15% per annum from October 9, 2015 to the date of complete payment.

Comprehensively taking account of the overall purport of the arguments as to Gap evidence Nos. 1 through 4, the plaintiff and the defendant are acknowledged to have prepared a loan certificate with the purport that the defendant shall pay KRW 21,00,000 to the plaintiff and deliver it to the plaintiff while engaging in money transactions from February 16, 2012.

According to the above facts, barring any special circumstance, the defendant is obligated to pay to the plaintiff 21 million won and 15% interest per annum from October 9, 2015 to the day of full payment, which is the day following the service date of the original copy of the instant payment order.

As to this, the defendant is a document in which the plaintiff filed a criminal complaint against the defendant as a fraud and received an investigation at the police station, without confirming the facts. Rather, since the defendant fully repaid the loan to the plaintiff until then, the above loan certificate is invalid. However, the evidence submitted by the defendant alone is insufficient to acknowledge the above fact, and there is no other evidence to acknowledge it.

Therefore, the defendant's argument is without merit.

Therefore, the plaintiff's claim of this case is justified and it is so decided as per Disposition.
