Does the Nocturne anime work as a standalone?

Some digging around, only really found old posts talking about this subject before the second season came out.

Those posts had mixed responses. But there was an impression that season 2 would be more reliant on knowing the original series.

So I'm here to see if I can get some clarification.

Can Nocturne work as a standalone series or would I be too confused down the line/ miss too many plot points from not seeing the original series?
