Content warnings:

1: Gender-bender, female-dom ABO, female E and male A, both leads are strong but the heroine is stronger, criminal investigation.

2: Some ABO elements won't be very relevant. This story greatly reduces the influence of pheromones and heats, to the point that they are almost nonexistent. In this ABO world, most people are Betas, while a special gender appears only once among several thousand or tens of thousands of people.

3: This story contains no BL couples. Please take note.

4: The criminal investigation story is entirely fictional.

5: The criminal investigation plot doesn't make logical sense. Every development and every piece of evidence exists to serve the plot.
