However, in accordance with the legal principle that the primary claim and the conjunctive claim cannot be tried separately, the primary Defendant Lessee Co., Ltd.’s appeal against the primary Defendant Counterclaim Co., Ltd., Ltd., and the scope of the judgment of this court was determined together with this judgment.
