[Request] Help me find the drama which I forgot the name after watching the trailer

Help me find this drama I don't remember it was Japanese or Korean. I saw the trailer of the drama couple of years ago on YouTube. And it was Thriller/Murder Mystery/ Detective type

So in the beginning of the trailer a man was laying on the floor in suit and his face was planted as he wakes up a classical music starts playing it was maybe Fur Elise by Beethoven. As the man walk out of the room some flashback/scenes are shown

The man was in black attire, he was in mid 30s and had really short stubble beard. Either he's the detective or someone who got falsely accused.

 I can't recollect the title but my memory says the title was something like "Murder" or something like that.

I think I watched it after 2016-71. I still remember I wanted to watch the drama after the release but I couldn't find it.
