B. Around March 2011, Defendant A entered into an employment contract with the Plaintiff to work as the head of the instant apartment management office. At the time of the contract, Defendant A agreed to compensate the Plaintiff for damages caused by Defendant A’s intentional or gross negligence.

C. From August 201 to January 31, 2012, Defendant B was the head of the instant apartment guard group. Defendant B was the head of the instant apartment building, and the construction business registration was completed on August 16, 201 with the trade name “D”.

On November 29, 2011, Defendant A contracted the construction of soundproof walls of the instant apartment (hereinafter “instant construction”) to Defendant B as the construction period from November 29, 201 to December 31, 201, and the construction cost of KRW 51 million (including value-added tax).

E. Although the instant construction was completed on December 26, 2011, some of the instant apartment residents filed a civil petition with the president of the instant council of occupants’ representatives, such as “No soundproofing effect exists due to the construction of a soundproof wall, the upper part of which was constructed was constructed by a wooden wave, and the cost of the steel scrap support is not solid,” against the president of the instant council of occupants’ representatives. On August 2012, 2012, the Plaintiff filed a civil petition with the Gwanak-gu Office, a competent administrative agency, to which the Gwanak-gu Office received public subsidies (25 million won).”
