2. The assertion and judgment

A. On April 8, 2010, the Plaintiff asserted that the Plaintiff repaid to the Deceased the principal of KRW 33 billion out of the borrowed amount of KRW 200 million.

The Plaintiff and the Deceased settled the loan obligation of KRW 200 million on the date of entering into the loan agreement of this case. In addition to interest on KRW 200 million, their opinions were different.

Therefore, the Plaintiff and the Deceased agreed to deduct KRW 30 million from KRW 100,000,000 borrowed under the loan agreement of this case, once the Plaintiff repaid the total of KRW 200,000,000 and thereafter presented evidence that the Plaintiff repaid the principal of KRW 33,00,000.

In light of the expression “a set-off of KRW 33 million” as of the fourth page of the complaint, the Plaintiff’s claim for return of unjust enrichment and the deceased’s claim.
