B. Article 1(2) of the above sales contract provides that “The purchase price referred to in paragraph (1) shall be paid in the presence of a practicing licensed real estate agent, unless otherwise stipulated,” and Article 6 provides that “if a buyer delivers money or goods to a seller as a down payment or a security deposit at the time of the contract, unless otherwise stipulated, the seller may repay a double payment of the down payment, and the buyer may waive the down payment and rescind this contract, until he pays the intermediate payment (if there is no intermediate payment agreement, unless otherwise stipulated, the remainder).” Article 4 of the special agreement provides that “10,000,000 won out of the sales contract shall be remitted, and the remainder down payment shall be KRW 20,00,000,000 from July 23, 2018.
