2. Summary of the plaintiff's assertion

A. The instant building is likely to cause safety accidents, such as aging, damage, or partial destruction, and thus, the Plaintiffs may refuse the lessee’s request for renewal of the contract pursuant to Article 10(1)7 of the Commercial Building Lease Protection Act.

Therefore, the instant lease contract was not renewed.

B. In addition, on December 27, 2018, the Plaintiffs notified D of the renewal of the instant lease contract on the condition that the lease deposit for the instant lease contract should be increased to KRW 250,000,000, monthly, and KRW 14,000,000. As such, the instant lease contract is not renewed.
