Upon reaching episode 5 of the new "BOSS2" Detective Drama I finally got to see exactly which character Haruka "Murasaki" Kinami is playing. I was a bit in the dark since her Dramawiki info led me to believe she was a recurring character in the show, but listed no name (at the time) for her part.
Well, seems Haruka is indeed playing a recurring character, a waitress who works at the restaurant/bar that the detectives frequent (i.e: have their goukons, LOL) and who seems to be developing a sympathetic interest in Tamayama "Linda" Tetsuji's character Katagiri. Hope this develops into an actual story here in upcoming episodes!
