Accordingly, around November 24, 2014, Defendant B sent a content-certified mail demanding the observance of designated items because the Plaintiff’s sales of coffee as its main item violates Article 9 of the instant lease agreement.

E. While the Plaintiff did not accept the above request of Defendant B and continued its business, the Plaintiff entered into a contract with F to transfer the entire goodwill of the instant store to F on January 22, 2015, and demanded the Defendants to change the lessee to F pursuant to Article 8 of the terms and conditions of the instant lease agreement. However, the Defendants are not obligated to accept the change of lessee as long as the Plaintiff transferred its business in the state of non-compliance with the designated items.
