1.The judgment of the first instance shall be modified as follows:

The defendant shall pay to the plaintiff KRW 308,000,000 and KRW 70,000 among them.

1. The reasoning of the judgment of this court citing the judgment of the court of first instance is the same as that of the judgment of the court of first instance, except for the following changes:

In the 8th judgment of the first instance court, "the result of this court's entrustment of appraisal to appraiser H" shall be changed to "the result of the court's entrustment of appraisal to appraiser H of the first instance court".

The 8th judgment of the first instance shall be amended from the 15th to the 5th judgment as follows:

D. Article 10-4 of the Restrictions on Commercial Building Lease Act provides that the opportunity to recover the premium shall be guaranteed to the lessee in order to prevent infringement of the expenses invested by the lessee or the designation or economic benefits formed as a result of the business activities conducted by the lessee by the cancellation of the lessor's contract and the rejection of the renewal thereof. In light of the legislative intent of the above provision, etc., it is reasonable to view that the court may reduce the amount of the above amount
