2. The parties' assertion
A. The Plaintiff’s claim 1) The Plaintiff, among the construction cost under the instant subcontract, completed the instant subcontract construction. However, the Plaintiff did not receive KRW 114,400,00 in total of KRW 104,000 and value-added tax of KRW 10,400,000. Therefore, the Defendant is liable to pay the Plaintiff the said KRW 114,40,000. The Defendant asserted that the construction cost should be reduced due to design change in the course of settlement with the ordering person, but there is no ground to do so, and there is no consent to the details of such settlement.
