2. According to the above facts of recognition as to the cause of the claim, the Defendants are jointly and severally liable to pay to the Plaintiff the remaining service payment amount of KRW 25,00,000 and damages for delay calculated at the rate of 15% per annum from May 13, 2016 to the date of full payment, as the Plaintiff seeks.

However, there is no evidence to prove that the Defendant Company paid the Plaintiff’s service payment to the Plaintiff’s partner company on behalf of the Plaintiff. Therefore, the above Defendant Company’s assertion is without merit.

4. Conclusion, the plaintiff's claim of this case is accepted as reasonable.
