Strawberry Night (2012)

Although the dramas are quite different in the sense that BOSS is a lot more comedic, there are still quite a few similarities with the 2 dramas.
Both have strong female detective leads who are both in change of investigation units.
Both have very well thought out crime cases.

-Strong female lead
-leadership & teamwork
-police & investigation dramas
-serial killers & murder investigations

Both dramas have strong casts, good acting, no romance but excellent chemistry between leads... recommended for all seasons of voice and Strawberry night series
