2. The Plaintiff asserts that, in the relevant case that became final and conclusive (Seoul High Court Decision 2015Na21760 decided March 31, 2016; hereinafter “related judgment”), the fact that the Defendant promised to repay the Plaintiff’s obligation to the Plaintiff, the Plaintiff cannot be found to be inconsistent with the foregoing without reasonable grounds.

According to the evidence No. 4-3 of the judgment of the court below, although the facts alleged by the plaintiff are acknowledged, the scope of the obligation that the defendant promised to pay on behalf of the plaintiff in the judgment is not specified.

Therefore, the plaintiff's above assertion is not accepted.

3. In conclusion, the judgment of the first instance is legitimate, and the plaintiff's appeal is dismissed.
