1. The plaintiff's claim is dismissed.

2. The costs of lawsuit shall be borne by the Plaintiff.

According to the evidence Nos. 1, 2, and 3, the defendant may recognize the fact that he/she contracted the above ground detached E, F, and Gdong construction work on October 28, 2016 every day on the housing construction of a stock company on February 2016, April 26, 2016, B detached Housing A, B, and C, and Ddong construction work on April 26, 2016, and on the housing construction of a stock company on October 28, 2016.

The Plaintiff supplied ready-mixeds necessary for new housing construction every day and suspended the supply due to failure to receive ready-mixeds price. The Defendant, the owner of the above housing, provided that he would be liable for the unpaid ready-mixed price and the subsequent supply price for the housing construction every day. Thus, the Defendant is obliged to pay 47,863,92 won to the Plaintiff.

According to the above facts and the evidence Nos. 7 and 8, the defendant is a contractor for a new construction of a detached house. The plaintiff can conclude a daily housing construction contract with the contractor for a new construction project and supply ready-mixeds. It is insufficient to recognize that the defendant, not the party to the supply contract, did not bear the obligation to pay the price under the supply contract, and that the defendant agreed to pay the unpaid ready-mixed price to the plaintiff, and there is no other evidence to prove otherwise.

Therefore, the plaintiff's assertion is not accepted.

The plaintiff's claim is dismissed on the ground that it is without merit.
