As such, the damages for delay during the said period are KRW 8,033,424 (i.e., KRW 81 million).

If the Defendant deducts KRW 400,00,00,000, it shall be KRW 49,033,424. Accordingly, the Defendant is obligated to pay to the Plaintiff the amount calculated at the rate of KRW 49,03,424 and the amount calculated at the rate of KRW 15% per annum under the Act on Special Cases Concerning the Promotion, etc. of Legal Proceedings from November 28, 2017 to the date of full payment.
