I'd rec:
- 99.9: Criminal Lawyer (a team of lawyers but they have to do some detective like work too to solve their cases)
- Siren (this one has a team of police officers but again they have to do a lot of detective like work to solve the biggest mystery and this one is full with unexpected plot twist until the end plus the female villain is great)
- Legal High (already in your PTW and highly recommended, it's funny and the cases are interesting)
maybe if you like legal high, how about watching hanzawa naoki (it's more serious than legal high with the same male lead)
