B. As to this, the Defendant: (a) sold the goods to a lower price that does not reach a half of the supply price for the goods supplied by the Plaintiff as well as the unfair transaction that had a significant difference between the supply price and the market price; (b) the unit price for the supply of the goods equivalent to KRW 90,576,000 per 1 square meter at the time of the supply on April 8, 2015 for the damage amounting to KRW 6,300 per 1 square meter at the time of the supply; and (c) KRW 6,500 per 1 square meter at the time of the supply on April 29, 2015 for the sales price; and (d) KRW 3,012 per 1 square meter at the time of the supply on April 29, 2015.

Accordingly, the Defendant asserted that the amount of damages equivalent to 31,392,000 square meters (=(6,300 - 3,012 x 9,000 square meters) and damages equivalent to 18,000 square meters for the supplied portion on April 29, 2015 x total quantity of 27,000 square meters x 9,184,000 square meters x 18,000 square meters [6,300 - 3,012 x 18,000 square meters], which is the sum of 90,576,000 square meters for the supply portion on April 8, 2015 (the Defendant asserted that the amount was 90,583,560 square meters from the preparatory brief on August 8, 2017, which appears to be a clerical error) is equivalent to the amount of damages.
