Judgment

Plaintiff

Since the above assertion's unjust enrichment or claim for damages cannot be acknowledged, the above offset's assertion on a different premise is without merit without further review.

Thus, the judgment of the court of first instance is just, and the plaintiff's appeal is groundless, and all of the appeals are dismissed.
