Unveiling the Secrets Behind Marriage
As the president of the "Wind Pattern Detective Agency," your daily work involves receiving clients who come seeking your services, all of whom share the same theme—failed marriages.
Your specialty lies in investigating and identifying the third party in these marriages, then using your prized SM techniques to utterly destroy their bodies and minds, helping your clients exact revenge.
One day, a woman with a sorrowful expression walks into your agency. She has a marriage that everyone envies—she comes from a prestigious family, and her husband is a university professor with a high social standing. Yet, she suffers from long-term emotional abuse and defamation, and seeks your help to uncover the truth.
To you, this seems like an ordinary investigation request, but your keen intuition tells you that the complexity of the matter may far exceed your expectations!
Doxxing
In the era of advanced social media, it is sufficient to provide powerful assistance for your preliminary investigation, carefully reviewing the clues and traces left by various target characters online, including their lives, careers, activities, itineraries... everything cannot be hidden. Tracking, following, monitoring, as a private detective, you can even exploit their desires and weaknesses in exchange for more intelligence.
Secretly Filming
To provide your client with solid evidence, sometimes it's necessary to approach the target undetected and install hidden cameras in their likely activity areas to obtain on-site evidence. Choose the installation locations carefully and cautiously, otherwise… you'll miss your chance, and the investigation will be in vain.
Revenge and Punishment
Once you've identified the third party who caused your client's marriage to break down, use various tools to torture and destroy her, taste her tears of regret, and complete your client's revenge!
