1. All appeals filed by the Defendant (Counterclaim Plaintiff) against the instant principal lawsuit and counterclaim are dismissed.

2. The costs of appeal shall be the principal lawsuit.

1. The reasoning of the court's explanation concerning this case is as stated in the part of the judgment of the first instance, except for the case where "960,000 won" in the 11th, 20 and 12th, 12th, 9 of the judgment of the first instance is "1,365,000 won", and therefore, it is consistent with the main sentence of Article 420 of the Civil Procedure Act.

2. The decision of the first instance court is legitimate, and the defendant's appeal is dismissed as it is without merit.

However, it is clear that the "960,000 won" in Paragraph (b) of Article 2 of the Judgment of the court of first instance is a clerical error in the calculation, and it shall be corrected to the "1,365,000 won".
