There's a new article about Dear M. The summary is police investigation is STILL GOING ON. (it's taking so long, the most complicated out of the bullying allegations from last year). Nothing is decided until the investigation is completely finished. Will update once an English translation is out.
Nothing is clear yet. Last known news regarding this was that police investigation is still going on. Park Hyesoo did film a movie but it seemed to be a previously canceled/postponed filming. You can't say she's innocent. Maybe the channel for Viki got deleted because the time is too long :/ It still says coming soon on iqiyi though.

They weren't meant to be together.
this is probably a better summary
