1. The reasoning of the court’s explanation concerning this case is that the reasoning of the judgment of the court of first instance is the same as the entry in the reasoning of the judgment of the court of first instance, except where the “from May 28, 2015, to May 28, 2016” was “from the lower part of the judgment of the court of first instance, to May 28, 2015.” Therefore, it is acceptable pursuant to the main sentence of Article 420

2. In conclusion, the plaintiffs' principal claim is dismissed as it is without merit, and the defendant's counterclaim claim is justified, and the judgment of the court of first instance is justified with this conclusion. Thus, the plaintiffs' appeal is dismissed as it is without merit. It is so decided as per Disposition.
