In the boiler pipes and hot water pipes, which are exclusive areas E-owned areas, the water level was reduced from the ceiling around the toilet to the floor, and the damage was caused by the damage of the ceiling and the remote area.

As a result, the Plaintiff was unable to receive rent of KRW 5,820,00 ( KRW 8,40,000 among the portion in December 2, 2017, KRW 1,600, KRW 500,000 for water leakage inspection expenses, KRW 500,000 for water leakage removal and fung removal expenses, and KRW 800,000 for 8,920,000 for stone table construction and delivery expenses, and the Defendant is obligated to pay the said money and damages for delay to the Plaintiff.
