In full view of the purport of the entire argument in the statement of evidence No. 1 in the judgment as to the cause of the claim against Defendant B, Defendant B Co., Ltd., the following facts are found: (a) Defendant B, by January 31, 2016, paid the Plaintiff KRW 16,00,000 as the construction cost of D Hospital until January 31, 2016; and (b) Defendant B, when Defendant B, paid the said amount, agreed to additionally pay KRW 14,00,000; and (c) Defendant B, when the said amount was due,
