1. The defendant's appeal and the plaintiff's incidental appeal are all dismissed.

2. The costs of appeal and the incidental costs thereof shall be individually considered.

1. The reasoning of the court's explanation concerning this case is as follows: "No evidence exists to acknowledge that the plaintiff requested an increase and failed to make a preparation for the trial" in the 5th, 9, and 10th, of the judgment of the court of first instance, except that the statement of evidence Nos. 3, 6, and 17 is insufficient to recognize the defendant's above assertion, and there is no other evidence to acknowledge it." Thus, this is identical to the statement of the reasons of the judgment of the court of first instance in the text of Article 420 of the Civil Procedure Act.

2. In conclusion, the judgment of the court of first instance is justifiable, and the defendant's appeal and the plaintiff's incidental appeal are all dismissed as it is without merit. It is so decided as per Disposition.
