Yeah you can tell it was axed. Everything wrapped up neatly and they didn't bother to bring up any of the previous arcs. Even the LN is on hiatus for 10 years, so this is dead dead.
Anyway, while it does feel like a harem, it's pretty much a guaranteed Murasaki win. Considering how much love they share with each other + OVA 2 last part when she told everyone to be just friends and let her be happy with Shinkurou.
