1. The Defendant shall pay to the Plaintiff KRW 50,00,000 and the interest rate of KRW 25% per annum from April 9, 2013 to the date of complete payment.

Comprehensively taking account of the overall purport of the arguments in the evidence Nos. 1-1 and 4, the Plaintiff entered into a lease agreement with the Plaintiff on October 8, 2012, setting the lease period of 48 months, monthly lease amount of 3,048,549 won, and delay damages rate of 25% per annum, and the Defendant jointly and severally guaranteed the obligation that B bears to the Plaintiff pursuant to the above lease agreement, and the lease agreement was terminated on April 8, 2013, and the principal of the obligation that B bears according to the above lease agreement was terminated as of March 29, 2018.

In relation to the evidence No. 1-1 (Lease), the defendant argued to the effect that B forged the column of joint and several sureties under the above lease contract, but considering the overall purport of the pleadings in each of the items No. 2-1 of the evidence No. 2-1 of the above lease contract, it can be acknowledged that the above lease contract contains the same facts with the seal imprint of the defendant's name affixed on the column of joint and several sureties under the above lease contract and the seal imprint of the defendant's certificate, barring any special circumstance, there is no evidence to prove that B forged the above column of joint and several sureties

Therefore, as a joint and several surety, the defendant is obligated to pay the plaintiff 50,000,000 won among the above accrued amount of debt and damages for delay calculated by the rate of 25% per annum from April 9, 2013 to the date of full payment, which is the day following the termination date of the above lease contract, to the day of full payment.

The plaintiff's claim of this case is reasonable, and it is so decided as per Disposition.
