2. The plaintiff's assertion and judgment

A. The gist of the assertion and the Defendant agreed to proceed with additional construction works other than the construction work under the instant construction contract. After the Defendant agreed to do so by a direct management method based on personnel expenses, the Defendant completed the construction, but the Defendant paid only KRW 79,260,000 out of the total construction cost of KRW 131,65,000 to the Plaintiff, and the Defendant is obliged to pay the unpaid construction cost of KRW 52,405,00 and delay damages therefrom to the Plaintiff.
