C. On May 11, 2016, the Plaintiff notified the Defendant that the instant lease agreement was terminated on the grounds that the Defendant did not perform its repair obligation under the instant lease agreement, and requested the Plaintiff to pay the lease deposit, the necessary or beneficial expenses incurred by the Plaintiff for the repair of C Apartment 105, and the amount equivalent to the heating expenses not paid during that period.
