The grounds for appeal by the plaintiff citing the judgment of the court of first instance are not significantly different from the allegations in the court of first instance, and even if the evidence submitted in the court of first instance shows the evidence submitted in this court, the fact-finding and judgment of the court of first instance are justified

Therefore, the reasoning of the judgment of this court is identical to that of the judgment of the court of first instance.

2. In conclusion, the plaintiff's principal lawsuit and the defendant's counterclaim are justified within the scope of the above recognition, and each of them shall be accepted, and the remaining principal lawsuit and counterclaim claims shall be dismissed as they are groundless.
