1. The Defendant shall pay to the Plaintiff KRW 30,00,000 and the interest rate of KRW 30% per annum from March 15, 2014 to the day of complete payment.

1. Determination on the cause of the claim

A. On March 14, 2014, the Plaintiff leased KRW 30 million to C on April 15, 2014 at the maturity of payment, set at 10% per month of interest, and on the same day, the Defendant’s joint and several guarantee of C’s obligation may be recognized either as a dispute between the Plaintiff and the Defendant, or as described in the evidence Nos. 1 and 2.

B. 1) According to the above facts, the defendant is obligated to pay to the plaintiff the interest or delay damages at the rate of 30% per annum which the plaintiff seeks within the scope of the agreement from March 15, 2014 to the date of full payment. 2) As to the defendant's failure to repay the plaintiff to the plaintiff at the due date, the defendant borrowed the above 30 million won prior to the plaintiff's due date, and the plaintiff borrowed the above 50 million won prior to the due date, with a higher interest rate of 80 million won and the due date for the joint and several surety, and the defendant refused to request the above 30 million won to withdraw the joint and several surety interest rate of 30 million won. Accordingly, the defendant's assertion that C purchased the above 30 million won and the above 30 million won interest rate was settled at the due date, and there is no new evidence to prove that C received the above 30 million won loan from the plaintiff and the above 300 million won loan again.

2. It is so decided as per Disposition by the assent of all participating Justices on the ground that the plaintiff's claim of this case is reasonable.
