Jdrama with mystery/action/ detective and romace

Can someone suggest me a Jdrama with action plot or mystery or detective work as its main plot ans romance as its sub plot???

 Origamy:

If you've seen/read the anime/manga Detective Conan, the live action is pretty good imo. I'd also suggest Erased which (also is based on a manga/anime and) has quite a bit of a mystery theme. 

I have seen the anime...grew up watching it actually....I’ll look into it !! Thank youuuu

 ShotaSidePart:

Boku no Yabai Tsuma- This has everything you asked for mystery, detective, and romance all together

Adding it to my list!thank you

Ohh this  is really close to what I am looking for.....thank you

hyakumanen no onnatachi / one million yen women - early eps are really slow youd be left wondering where the heck is it heading, around ep 7-10  it gave me a shiver, it at least gave you somewhat a nice ending
