2. The principal lawsuit and the motion for succession participation, and the judgment thereon

A. The plaintiff and the intervenor asserted as the principal lawsuit that the defendant continued to possess and use the second floor of the commercial building even if the lease of the second floor of the commercial building has expired after they acquired the ownership of the commercial building, and thus, the defendant is obligated to return unjust enrichment acquired by the defendant by transferring the second floor of the commercial building to the plaintiff and by occupying and using the second floor until its delivery.

As the intervenor acquired ownership of a commercial building during the course of the lawsuit in this case, the intervenor asserts that the intervenor had the obligation to deliver the second floor of the commercial building to the intervenor and that the defendant has the obligation to return the unjust enrichment from the possession and use of the building to the plaintiff (the part concerning the claim for return of unjust enrichment).

B. On August 20, 2015, the Plaintiff acquired a commercial building from C to succeed to the lessor’s status against the Defendant, and subsequently, on August 2017.
