1. Revocation of the first instance judgment.

2. The Defendant shall pay to the Plaintiff KRW 1,80,000 as well as the full payment with respect thereto from September 8, 2018.

In full view of the statements in Gap evidence Nos. 1, 3, 8, and 9 (including more than one number), witness C’s testimony, response results of the first instance court’s request for financial transaction information to the D Bank, and the whole purport of the pleadings, the plaintiff decided to lend 1,80,000 won to the defendant on August 30, 2015, a monthly interest rate of 2% and November 30, 2015, which is three months after the due date, as of November 30, 2015, and remitted 1.8 million won to the defendant’s account.

According to the above facts of recognition, the defendant is obligated to pay to the plaintiff 1,80,000 won borrowed and the damages for delay calculated at the rate of 15% per annum from September 8, 2018 to the date of full payment as the plaintiff seeks.

Thus, the plaintiff's claim is justified, and the judgment of the court of first instance, which has different conclusions, is unfair, so it is decided as per Disposition.
