2. The parties' assertion

A. It is true that the Plaintiff signed and sealed in the column of other special terms and conditions of the Labor Guarantee (Evidence A No. 2) for the instant modified obligation.

However, in order to claim that the letter of guarantee prepared by the Plaintiff is valid for the obligation to change in this case, it will be an important part of which the Plaintiff prepared the letter of guarantee for the obligation of anyone, but the letter of guarantee for the obligation of the Plaintiff is not the body of the Plaintiff.

In addition, the Plaintiff signed and sealed the Defendant’s employees on the ground that the Defendant’s employees did not explain any other debt at all due to changes in the repayment method of the Defendant’s guaranteed obligation and the changed debt (the repayment of the principal and interest each month only with interest repayment) and the loan period (the extended 10 years on a yearly basis).

The evidence No. 2 states that “A shall receive the basic terms and conditions of credit transaction, the transaction agreement, and this guarantee, clearly and explain the important contents,” rather than the Plaintiff, that “I have explained about the debtor’s current status of debt, the existence of arrears, etc.”.
