Mingke: How Can I, a Fox Fairy, Solve the Case?

[Two men, don't break the main cp, main plot, supplement daily life, no abuse (probably). The protagonist Huhu is chaotic and neutral, and does whatever comes to mind. Because he has lived for a long time, he knows a little bit about all skills. Asaba Ayako is a little fox fairy who is more than 3,000 years old. One day, he accidentally got a little guy who called himself the system. In order to save his former lover, he traveled to the world of Conan. But as the days passed, Asaba Ayako gradually realized that something was wrong... Why are there more and more cases? I'm obviously just an ordinary fox fairy! Why should I be asked to solve the case? ! ! (This is my first time writing a long story, so please forgive me if it's not good. If you have any comments, you can give them. I will change them after I see them~)
