2. The parties' assertion

A. On October 2016, the Plaintiff’s summary of the Plaintiff’s assertion was asked by the Defendant to lend KRW 4 million to the Plaintiff’s attorney-at-law’s appointment fee in relation to the business of a small number of power co-generation generation, and that KRW 2 million was set off against the Plaintiff’s attorney-at-law’s claim, and the remaining KRW 2 million was remitted directly to C.

Until December 14, 2016, the Defendant: (a) agreed to return the loan certificate of this case to the Plaintiff by adding a penalty of KRW 4 million to a penalty of KRW 4 million where a small power unit operator operated the small power unit and did not produce electricity until then; and (b) the Defendant returned only KRW 2 million to the Plaintiff as the Defendant did not produce electricity until now.

Therefore, the defendant's remaining 6 million won is added to the plaintiff.
