[Reasons for Recognition] Evidence No. 1, Evidence No. 4, and the purport of the whole pleadings

2. The Plaintiff’s efforts to assert that the Defendant received a successful bid of KRW 632 million for the instant construction work, the Defendant paid KRW 14,8890,000,000,000 except for KRW 48,3110,000,000 from the Defendant, but the Defendant agreed to receive KRW 11,289,000,000,000,000,000 for the instant construction work, based on the successful bid of KRW 576,000,000,000,000,

Since the Defendant paid only KRW 70 million upon completion of the instant construction and payment of the full construction cost from B University, and did not pay the remainder of KRW 42890,000,000, the Defendant is obligated to pay the Plaintiff KRW 42890,000 and delay damages.

3. In light of the fact that the Defendant paid KRW 70 million to the Plaintiff with respect to the instant construction project, etc., the Defendant appears to have affected the Plaintiff’s business ability to receive the successful bid of the instant construction project, but the Defendant’s testimony is alone the statement of No. 2, and the witness C’s testimony.
