B. Around November 18, 2010, F lent 1 column of the instant building to Plaintiff A to KRW 40,000,000, the sub-lease deposit, and around January 6, 2011, F sub-lease 50,000,000 to Plaintiff B another column of the instant building.

C. The F failed to pay the monthly rent to the Defendant, and the Defendant visited the instant building in order to receive unpaid monthly rent around October 2012, and F became aware of the fact that F subleted the instant building to the Plaintiffs without the Defendant’s consent.

Accordingly, F posted a letter to the effect that the Plaintiff A and B was able to receive the sub-lease deposit and return the sub-lease deposit to Plaintiff A and B, and the Plaintiff A and B posted a letter to the effect that they were able to keep their pictures and boms on the Internet Neneber “H” real estate page around January 2013.

F. On March 15, 2013, Plaintiff D (hereinafter “D”) confirmed Plaintiff B’s posting comments, and subsequently set the room of the instant building as KRW 50,000 from F to KRW 50,000 from March 15, 2013, and the joint Plaintiff C (hereinafter “C”) of the first instance trial verified Plaintiff A’s posting comments, and thereafter, the instant building from F on July 29, 2013.
