I have only romanced one character in the game, that being Neve. I did notice that she had a lot more chemistry with Lucanis than she did with my character (that I designed to be as attractive as a male character could be, btw). But I rose to the challenge lol.
I actually like the characters a lot, and I wasn't sure if Neve is just a bit detached or closed off in general, which seems to be her personality somewhat. What I did find irksome is that after every single mission, Neve would be hanging out with Lucanis at the Lighthouse, or he would be hanging out with her. How come Rook doesn't get a visit? lol
