Accordingly, the Plaintiff was dispatched to the instant construction site from July 31, 2017 to August 7, 2017, and then paid KRW 1,8910,00 to workers on behalf of the Defendant. Accordingly, the Defendant is obliged to pay KRW 1,891,00 to the Plaintiff.

Therefore, the defendant is obligated to return the above KRW 18910,00 to the plaintiff as unjust enrichment.
