1. On February 14, 2007, the plaintiff lent 10 million won interest rate of 24% per annum to C on March 13, 2007 and the due date of repayment of 24% on March 13, 2007. Since the defendant jointly and severally guaranteed the above loan debt, the defendant is jointly and severally liable with C for the above loan debt. However, the defendant's portion of the evidence No. 1 cannot be used as evidence since there is no evidence to prove the authenticity of the above loan debt, and there is no other evidence to prove that the defendant jointly and severally guaranteed the above loan debt. Thus, the plaintiff's above assertion is without merit.

2. Thus, the plaintiff's claim against the defendant should be dismissed as it is without merit. Since the part against the defendant in the judgment of the court of first instance as to the defendant is unfair with different conclusions, the part against the defendant in the judgment of first instance which accepted the defendant's appeal is revoked, and the plaintiff's claim against the defendant is dismissed as per Disposition.
