1. Basic facts

A. The Plaintiff is a stock company established for the purpose of advertising planning, marketing, and advertising agency business.

B. The Defendant entered into a comprehensive advertising agency contract with C (the former mission “D”) that provides the mobile content platform service (the former mission “C” and the “C” rather than distinguishing between the platform and the service provider company) to be a corporation established for the purpose of advertising, advertising agency, etc., and has performed the duties of linking the advertiser’s C advertisements.

C. Around June 2017, the Defendant’s representative director E requested for the interference of the Plaintiff’s representative director F with the company director of the Plaintiff, who has a lot of connection with the insurance company, and the advertiser of the insurance company to publish the advertisement in C.

Accordingly, the Plaintiff proposed C Advertising to G Co., Ltd., H Co., Ltd., I, I, J Co., Ltd. (hereinafter “Co., Ltd.”) from around that time.

As a result, on July 5, 2017, the Plaintiff entered into a C Advertising Agreement with the Defendant acting as the agent of G, and on October 24, 2017, the Plaintiff entered into C Advertising Agreement with the Defendant acting as the agent of K as well.

E. Meanwhile, in order to publish I’s advertisement in C from the end of June 2017, the Plaintiff consulted with the officer in charge of I’s work process and unit price, delivered the agreed contents to the Defendant, provided C’s guidelines to the Defendant, and provided I with the advertising design upon consultation with I, and subsequently, provided I with the advertising design.

F. However, during the foregoing work, there was a problem of disagreement between I and C with respect to the provision of customer personal information.

In order to solve this problem, the plaintiff and the defendant agreed to enter only the defendant into the contract as an agent (C), but the agreement between the plaintiff and the defendant related to I's advertisements is made.
