1. Determination as to the cause of claim

A. The fact that there is no dispute between the parties is calculated on the basis of the annual payment date of Plaintiff A B from July 1, 2010 to June 30, 2013 based on the annual payment amount of lecture fees of KRW 80 million as Plaintiff A with the same contract deposit and KRW 50 million, ② 55% of the relevant section of KRW 200 million to KRW 40 million, ③ 60% of the relevant section of KRW 400 to KRW 600 million, ④ 65% of the amount of KRW 80 million to KRW 80 million, ⑤ 50% of the amount of tuition fees of KRW 70% of the amount of KRW 80 million to KRW 50% of the monthly payment date of the contract for Plaintiff A and the Defendant who did not provide the educational facilities without justifiable grounds during the contract period, ③ in the event that the Defendant did not assign the comprehensive contract amount of KRW 100,000,000,000 to KRW 160,000.

(2) The Plaintiffs concluded an agreement with the Defendant from July 2010 to December 2010.

3) The sales amount arising from the Plaintiff’s lecture during the above period is KRW 490,449,858, and the Defendant paid KRW 26,905,465 to the Plaintiff as a lecture fee. The sales amount arising from the Plaintiff’s lecture during the above period is KRW 177,956,618, and the Defendant paid KRW 15,805,098 to the Plaintiff B as a lecture fee, and the Defendant did not pay the down payment. 4) The Plaintiffs constitute “the case where the Defendant did not pay the lawful price or the down payment for the lecture without any agreement,” and thus, the Defendant terminated each contract of this case by delivery of the duplicate of the complaint of this case.

B. Therefore, barring any special circumstance, the defendant shall pay to the plaintiff A KRW 501,634,365.
