2. Determination

A. There is no dispute between the parties that the instant lease agreement, which was implicitly renewed, was terminated by the Plaintiff’s termination notice as to the cause of the claim, and the fact that the boiler with the instant real estate subject to the Defendant’s repair obligation, was replaced by the Plaintiff’s 800,000 won as the boiler was cut off and replaced by the Plaintiff’s 80,000 won. As such, the Defendant is obligated to pay the Plaintiff the lease deposit amounting to KRW 40 million and KRW 80,000,000,000 for boiler replacement costs

B. As to the Defendant’s defense, the Defendant asserted that the amount of damages should be deducted from the lease deposit, on the ground that the Plaintiff’s negligence on the part of failing to take preventive measures against the dynamics against the water pipe and boiler, caused damage to the water pipe and boiler’s ceiling of the first floor of the instant real estate, and caused damage equivalent to approximately KRW 15,004,00 with the repair cost, such as flooding the underground room, etc., but the testimony by the Defendant or the witness C alone caused the Plaintiff’s negligence.
