2. Determination as to the cause of action

A. The gist of the plaintiffs' assertion: (a) the defendant entered into an exchange contract with the terms that the plaintiffs shall pay the corresponding price to the plaintiff by June 8, 2018 (hereinafter "the contract of this case"). However, since the defendant's obligation to pay Costato the plaintiffs was impossible, the plaintiffs cancelled the contract of this case and were returned to the defendant due to restitution. However, if the plaintiffs received this, the amount of 1/3 of the price (600,000 won per opening) compared to the market price at the time when the plaintiff paid Costato the defendant, the defendant is liable to compensate the plaintiffs for damages calculated by converting the amount into the market price of June 8, 2018.

In addition, since the defendant deceivings the plaintiffs as if he had entered into a direct supply contract with the headquarters of Lone Starwaken, it could bring about a certain amount of 371 interest rates by deceiving them as if they could bring about a certain amount of loss, and then returned 1.5 million interest rates to the plaintiffs.
