Just finished, It's very very good. Loving the story so far, the story and characters are definitely this AVN's strong suit. The visuals are also great too, so overall it was a very enjoyable experience all the way through.
Lucy is my favorite LI as of now, Charlotte and Emma are both close fighting for my 2nd spot, however I'd have to have to edge it to Charlotte. Mainly because I like Emma more as just a character rather than an LI, because so far the MC's been more like a father figure/protector for her, and there's been no actual romance between them, it's been hinted at, but nothing concrete yet. Lucy on the other hand is not only an amazing character, but is easily my favorite LI, the romance between them has been built up perfectly, and she doesn't have the emotional baggage that comes with Charlotte. I love Charlotte as a character, but as an LI it's still very much slow progress with her, and I love the relationship between the MC and Charlotte and how it's developed over the course of the game. However as an LI I feel like currently Lucy is just far better than the rest.
Meanwhile, Suzi I have no interest in, not attracted to her that much, don't like her personality all too much, and she's been the least interesting one to me in terms of a potential love interest. I think she's the only main character I'll completely skip on.
As far as the side characters, I'm not interested in either Kaylah or Selena to be honest, they are side characters anyways, so I don't really see the point in pursuing anything with them. Charlotte is the better Kaylah anyways.
