I found out something interesting in this process. It is possible to resurrect a failed romance. In this particular game save the Juliet romance was progressing much faster than the others so I intentionally tanked it early on so I wouldn't have to keep ducking it's ending scene while I leveled the others. Now we all know failing a romance resets it to 50 but you can still level it in those night time events where you chose to spend some time with someone in the tavern so after I finished getting the other three love interests to 100 I started focusing on leveling Juliet's romance back up to 100 which took quite a while since I was almost constantly reloading to dodge the 3 other romance ending scenes that kept popping up but once I got her back to 100 her second to last romance scene (The one where she's injured and you have to insist on helping) popped up and I was able to complete her romance even though I intentionally failed it early on in the game.
That said, here's my evaluation of the four...
Juliet was my favorite.
My overall review of the game...
I liked the characters and the whole pirate setting of the story. That was all pretty cool.
I didn't like the sin/virtue system that seemed to be judging my every move.
I also kind of felt like the skill/profession system the story was wrapped in felt kind of flat. Arbitrarily clicking a button that randomly raises a skill just wasn't very entertaining or engaging. It just felt like a time killer.
I understand this will be the last in the Heileen series but if you guys ever do something like this with a pirate setting in the future it might be cool to wrap it in an RPG battle system like Loren. There could be a map like in Loren but instead of a land mass there would be open ocean with islands with ports they could visit and random locations out in open sea (like "the plains" when doing the quest in Loren to find the cure) where there could be battles with other pirate ships or military ships trying to bring the pirates to justice.
Something like that I'd find a much more engaging way of having the story unfold.
