The first instance court.

1. The reasoning for the court's explanation of this case is as stated in the reasoning of the judgment of the court of first instance, except for the rejection of witness D who is insufficient to recognize the plaintiff's assertion as additional evidence submitted by the court of first instance. Thus, it is recognized as it is in accordance with the main sentence of Article 420 of the Civil Procedure Act.

Thus, the plaintiff's claim of this case is dismissed as it is without merit, and the judgment of the court of first instance is just, and the plaintiff's appeal of this case is dismissed as it is without merit (the part concerning the reduced damages for delay in the judgment of the court of first instance was invalidated). It is so decided as per Disposition.
