However, in violation of this agreement, the Defendant concluded a lease agreement with the security deposit at KRW 170,000,000, and did not notify the Plaintiffs thereof, and the obligation to deliver documents necessary

As such, the Defendant’s act constitutes the nonperformance of the obligation under each of the instant sales contracts, the Plaintiffs cancelled each of the instant sales contracts on the grounds thereof, and sought payment of KRW 20,000,000, which is a double of the down payment with compensation for damages.
