1. As to the cause of claim

A. On March 15, 2016, the Plaintiff issued the instant vessel to the Defendant, and on March 30, 2016, the Plaintiff paid the instant vessel amounting to KRW 27,00,000 for the period from March 30, 2016 to December 31, 2016, with the Defendant, from March 30, 2016 to December 31, 2016.
