1. The Defendant shall pay to the Plaintiff KRW 110,00,000 and the interest rate of KRW 15% per annum from June 16, 2016 to the date of full payment.

In full view of the entries in Gap 1 through 5, Eul's testimony, and the purport of the entire pleadings, the plaintiff shall, at the defendant's request on October 2007, make an investment in the business of running the water skiing ground operated by the defendant. The plaintiff paid a total of KRW 140 million to the defendant on October 31, 2007 and KRW 40 million on August 2008. The plaintiff agreed to receive an investment refund from the defendant during the business of running the water skiing ground after the end of 2010 to 2011, and pursuant to the above agreement, the plaintiff received a return of KRW 30 million from the defendant on May 31, 2012.

Therefore, the Defendant is obligated to pay to the Plaintiff the remaining amount of KRW 10 million (=140 million - 30 million) and damages for delay.

If so, the plaintiff's claim is reasonable.
