B. On February 16, 2007, the Plaintiff prepared a real estate sales contract that causes the purchase price of 984,150,000 for E and the instant loan, and received the down payment of 50,000,000 won.

[Reasons for Recognition] Each entry of Gap 1-5 evidence, the purport of the whole pleadings

2. The Plaintiff asserted that Defendant B, who sold the apartment of this case more than KRW 1,200,000,000, agreed to sell the apartment of this case at the price of KRW 1,00,000 in return.

On February 16, 2007, the apartment house of this case was sold to E in KRW 1,200,000,000, and according to the above agreement, Defendant B was paid KRW 100,000,000 to Defendant B. At the time, Defendant B was using the passbook due to credit problems, and requested to deposit it into the passbook, and transferred the above KRW 100,000,000 to Defendant C.

However, the sales contract between the Plaintiff and E was concluded, and the Plaintiff thereafter sold the instant apartment to others.

Therefore, there is no obligation for the Plaintiff to pay KRW 100,000,000 to Defendant B. Therefore, the Defendants should return the said KRW 100,000,000 to Defendant B as unjust enrichment.
