1. The plaintiff's appeal is dismissed.

2. The costs of appeal shall be borne by the Plaintiff.

The purport of the claim and appeal is the purport of the appeal.

1. On May 9, 2006, the Plaintiff agreed to receive 150% of the principal by June 30, 2006 when lending KRW 50 million to B on May 9, 2006. The Defendants jointly and severally guaranteed the above loan obligations, and thus, the Defendants are liable to pay the above loan and the damages for delay to the Plaintiff.

On the other hand, Gap evidence Nos. 1 and 8, which correspond to the plaintiff's assertion, cannot be used as evidence because there is no evidence to prove the authenticity of the evidence other than the statement No. 7, which is hard to believe, and each statement of Gap evidence Nos. 2 through 6 (including the number of evidence) is insufficient to recognize the plaintiff's assertion. Since there is no other evidence to prove it, the plaintiff's above assertion is without merit.

2. Thus, the plaintiff's claim of this case is dismissed as it is without merit, and the judgment of the court of first instance is just, and the plaintiff's appeal is dismissed as it is without merit. It is so decided as per Disposition.
