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

2. The costs of appeal shall be principal lawsuit and counterclaim.

The reasoning for the court's explanation of this case is to delete the part of "(the defendant is dismissed from the day after delivery of a counterclaim)" from 9th to 10th, 14th, 14 of the judgment of the court of first instance (the defendant is dismissed from the day after delivery of a counterclaim) (the defendant modified the purport of the part of the damages for delay due to the amendment of the Act on Special Cases Concerning the Promotion, etc. of Legal Proceedings through filing an application for change of claim and cause of claim in the first instance court). Thus, it is identical to the reasoning for the judgment of the court of first instance.

Thus, the plaintiff's main claim is dismissed as it is without merit, and the defendant's counterclaim is justified, and the judgment of the court of first instance is just in conclusion, and all appeals against the plaintiff's main claim and counterclaim are dismissed.
