In the event that the buyer has agreed to accept the collateral obligation of the right to collateral security regarding the subject matter of sale in lieu of the payment of the purchase price with regard to the obligation to return the lease deposit against Do Governor AC, the buyer cannot be construed as bearing the obligation to pay the remainder after deducting the amount of the obligation from the purchase price, and barring special circumstances, the buyer fulfilled the obligation to pay the remainder after paying the remainder after deducting the amount of the obligation from the purchase price. However, barring any special circumstance, the buyer shall be deemed to have failed to perform the obligation when there is a special reason to evaluate that the obligation is identical to the payment of the purchase price by delaying the performance of the obligation and delaying the performance of the obligation (see Supreme Court Decision 98Da25184, Oct. 27, 1998; Supreme Court Decision 98Da25184, Oct. 27, 199).

In addition, it is insufficient to recognize that the Plaintiff suffered a profit that does not pay the purchase price equivalent to KRW 50,000,000 without any legal source and thereby incurred a loss equivalent to the same amount to the Plaintiff.
