The defendant.

A. A. Around June 2005, the primary claim is made by the Defendant, “The Defendant may receive a refund of more than two times after five years if it has invested surplus funds, and the principal will be preserved at least. As such, it is necessary to maintain the credit performance until the branch is promoted. As such, an investment should be held for about five years, and an investment should be made in multiple names, as it is helpful for credit performance, and a part of it will be invested in a stock operations personnel in order to increase the return of profit.” Around that time, the Defendant entered into such investment agreement with the Defendant, and accordingly, invested KRW 60 million to the Defendant on July 13, 2005.

Since five years have elapsed since the date of the above investment, the defendant is obliged to pay at least KRW 600 million, the principal of the investment, and damages for delay to the plaintiff.

B. Even if the Defendant’s receipt of KRW 600 million from the Plaintiff was not based on the investment agreement, the Defendant, without any legal ground, obtained benefits from the Plaintiff, and thus, the Defendant is obligated to pay the Plaintiff the amount of KRW 600 million with unjust enrichment and delay damages.
