1. The defendant's appeal is dismissed.

2. Of the appeal costs, the part arising between the Plaintiff and the Defendant is the Defendant.

1. The defendant's grounds for appeal citing the judgment of the court of first instance are not significantly different from the argument in the court of first instance, and the fact-finding and judgment of the court of first instance are justified even if each evidence submitted to the court of first instance was presented to this court.

Therefore, the reasoning of this court's judgment is the same as that of the first instance court's judgment, and it is citing it by the main text of Article 420 of the Civil Procedure Act.

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