Where can I see Vincenzo (Kdrama) with German sub?

At the moment I see the drama "Vincenzo" very often on my fyp and I really want to watch it, only it's not available on Netflix, there's a gray screen and no date when it should appear. Does somebody has any idea? It can't be seen on viki either: ')

There would be Dramacool, but I don't know if it's legal, as there have been a lot of discussions…
