1. The Defendants jointly and severally agreed to the Plaintiff KRW 72,084,60 and Defendant A Co., Ltd. from April 24, 2015.

Comprehensively taking account of the statements in Gap evidence 1 through 5 (including paper numbers), Eul evidence 1 and 2 and the purport of the entire pleadings in witness Eul's testimony, the plaintiff supplied ready-mixeds equivalent to KRW 122,084,600 to the construction site, the owner of the building, and received KRW 50,000,000, as part of the price, between July 31, 2014 and October 14, 2014; Eul was permitted to use the name of the defendant corporation; on July 21, 2014, between the plaintiff and the defendant corporation in the name of the defendant corporation Eul (hereinafter referred to as "the contract of this case"); the plaintiff issued the tax invoice on supply of the above ready-mixed to the defendant corporation Eul; and at the time of preparing the contract of this case, the person in charge of the construction site as a joint guarantor of the defendant corporation's seal impression was also acknowledged as having been signing the contract of this case.
