#Let’s popularize some knowledge:

"Sponsorship Agreement" or "Paid Companionship Agreement" - there are significant legal issues from a legal perspective, and even if signed and fingerprinted, it is likely to be invalid or even suspected of being illegal.

Violation of public order and good morals principle (Article 153 of the Civil Code)
The exchange of "sexual acts" involved in this agreement constitutes behavior that violates social order and good morals, and the court may legally determine the contract to be invalid.

Suspected of concealing illegal purposes under a legal guise.
The surface states "accompany" and "activity", but the content clearly includes terms such as "engaging in sexual acts", which may constitute the facts of prostitution or organizing prostitution.
