2. Summary of the parties' arguments

A. The plaintiffs 1) delegated the purchase price of the real estate of this case to the defendant, and paid the price of KRW 130 million to E. The defendant did not pay the above money to E, or even if he paid the above money, the defendant did not perform its duty to manage the business so that the plaintiffs can acquire ownership of the real estate of this case with the due care of a good manager, and eventually did not transfer the ownership of the real estate of this case to the plaintiffs. Therefore, the defendant was not obligated to pay the plaintiffs the amount equivalent to the amount paid by the plaintiffs to the defendant as the compensation for unjust enrichment or default. Thus, the defendant is obligated to pay the plaintiff A the purchase price of KRW 43,330,00,000,000 to the plaintiff Eul, 433,340,000,000 won to the plaintiff Eul, and 43,43,000,0000 won to the plaintiff C, respectively.

B. The defendant only introduced the real estate of this case to the plaintiffs, and there was no delegation from the plaintiffs to purchase the real estate of this case.
