2. Judgment on the plaintiff's assertion

A. The plaintiff asserted that the plaintiff leased the apartment of this case from F to KRW 15,00,00,000, and completed the delivery of the house and resident registration. Thus, the plaintiff is a small-sum lessee with the right of priority repayment under the Housing Lease Protection Act.

Therefore, the amount of KRW 15,00,000 out of the Defendant’s dividends should be distributed to the Plaintiff. As the Plaintiff did not submit the instant lawsuit even after filing the lawsuit, and the Defendant paid the total amount of dividends, the Defendant sought restitution of the unjust enrichment of KRW 15,00,000 against the Defendant.
