Seeking a criminal drama

One of them was a policewoman who could easily see through other people's psychological activities (I don't know how to describe it). Anyway, the people around her were quite afraid of being seen through by her, so she didn't have any friends. The other policemen didn't have much of an impression of her. I think there was a nickname called Viper (I'm not sure)... There was a story about a pair of twins, and the sister was silly and couldn't tell the difference. It was probably because one of them committed suicide for the other. The songs in the drama were also very good!
I've been looking for so long that I'm about to cry... Thank you, big shots

Answer 1

For a criminal drama, you can refer to the following example:
Detective Conan was a Japanese mystery drama created by Ishikawa Hideki, which first aired in 2002. The drama tells the story of the detectives of the Tokyo District Court's Criminal Detective Agency solving various criminal cases.

The main character of the drama was called "Criminal Detective Agency", Koizumi. He led a group of smart, witty, and experienced detectives to solve all kinds of complicated criminal cases. Other than Koizumi, the other detectives included Kyoko Mori (the female lead was an excellent female detective), Kato Seirou (the male lead was a smart and witty detective), Sano Isamu (the male lead was a strong detective), and so on.

The drama received widespread praise, not only in Japan, but also in mainland China, Taiwan and other places, gaining high popularity and influence.
