1. All appeals filed by the plaintiffs are dismissed.

2. The plaintiffs' preliminary claims are all added at the trial.

1. The reasoning of the court's explanation concerning this case is as follows, and the reasoning of the judgment of the court of first instance is the same as that of the judgment of the court of first instance, except for adding the judgment on the conjunctive claim newly asserted by the plaintiffs in the court of first instance as set forth in paragraph (2) below. Thus, it is acceptable as it is by the main text of

2. The plaintiffs, although the facts of the conjunctive claim are the number of buyers of the building of this case who purchased the building of this case by applying a discount rate higher than the plaintiffs, they are willing to compensate the plaintiffs for mental damages equivalent to the amount of the primary claim by deceiving them to be subject to the highest discount rate for the sale price of this case. However, there is no evidence to acknowledge this. Thus, the plaintiffs' conjunctive claim is without merit.

3. In conclusion, the plaintiffs' primary claims of this case are all dismissed as they are without merit, and the judgment of the court of first instance is just in conclusion. Thus, all of the plaintiffs' appeals and preliminary claims added at the court of first instance are dismissed as they are without merit. It is so decided as per Disposition.
