The Plaintiff supplied processed goods of KRW 178,845,891 to the Defendant from September 2014 to May 2016, but the Plaintiff paid KRW 159,008,00 as the price of goods.
[Ground of recognition] Facts without dispute, Gap evidence 1 to 6 (including additional number), the purport of the whole pleadings
