2. The costs of lawsuit are assessed against the plaintiffs.

1. The Plaintiffs asserted that they concluded an authorization, permission, design, and real estate consulting service contract relating to new construction of a building with Defendant C, the agent of Defendant C, after purchasing real estate.

As the primary defendant C is a contracting party, the primary defendant D is a non-authorized representative or a contracting party, and the primary defendant D is obligated to pay 32,942,360 won for the purchase of real estate and for consulting fees of 25,00,000 won to the Plaintiff Co., Ltd.

2. The testimony of the witness E alone is insufficient to recognize that the plaintiffs entered into a contract with the defendant or the preliminary defendant, and there is no other evidence to acknowledge it.

3. Conclusion, the plaintiffs' claims against the defendants are dismissed in entirety.
