1. The Defendants are jointly and severally liable to the Plaintiff for KRW 87,00,000 and 5% per annum from July 26, 2018 to March 6, 2019.

The plaintiff's facts of the cause of the claim of this case are as shown in the annexed sheet "the cause of the claim", and the evidence Nos. 1 through 7 can be recognized in full view of the whole purport of the pleading.

As to this, the defendant C signed the document No. 2 (Certificate of Investment Contract) due to the pressure of the defendant C, and the above document has no effect on himself, but it is rejected as there is no evidence to acknowledge the above assertion.

Therefore, the Defendants are jointly and severally liable to pay to the Plaintiff the remaining principal amount of KRW 87,00,000 and damages for delay as prescribed by the Civil Act from July 26, 2018 to March 6, 2019, which is the date of service of a copy of the complaint, to March 6, 2019; 15% per annum from the next day to May 31, 2019; and 12% per annum from the next day to the date of full payment.

Therefore, the plaintiff's claim against the defendants is justified.
