Evil Minds 2 (2016)

Both are detective dramas
both have bromance between two leads
both have psychological aspect in solving cases

Both dramas deal with mental health issues and the crimes committed by the people with those issues
Evil minds is more about solving the crimes committed by them after the fact not treating them but also the male lead has a mental disorder that was addressed in the drama

I am now in the second season and it is just as intriguing. I came to this site to find out if the actors were in any other similar drama. They are excellent especially the two male leads. The only thing I can compare this drama to is the Korean drama The Voice starring Jang Hyuk. There is a film starring Wallace Huo called Inside or Out, with Simon Yam and coincidentally Jang Hyuk. Don't miss either of them or both seasons of Evil Minds

Both dramas are detective dramas solving criminal cases
Both dramas have good partnership between older detective and younger profiler
