Chemistry was an important element in the stories in season 1. But it seems this season is devoid of chemistry. There is no chemistry between Eun sol and the Doctor baek. Neither is there a chemistry between the team members. The cases were interesting overall but there was less involvement of the leading lady, Eun pro. This was a crucial element of Investigation couple. It would have been better if the doctor beak warmed up to others a bit. No character development. Plus Stella Hwang was much better than Sally. Please bring her back. The series simply lacked the fun element. Season 1 was waaaaayyyy better in my opinion. Overall worth a watch.
