I discovered something:
When I (generosity 1, honor 1) speak with Phaea (honor 1) when I look like a barbarian (long beard and that mohawk-like haircut) she answers with ,,em... yes, well". But when I go to Imperial town, go to barber and get imperial style hair and beard then she answers with ,,Yes... Yes. We should, em, discuss this". I checked this multiple times with different approaches (,,perhaps you an I..." and ,,I wish to offer my hand in marriage") always with the same effect.
I think it's the matter of your face (sorry to say that
) and maybe your traits what answer she always gives you.
Edit:
I checked also approach without scars on the face (I had scar through the eye earlier). The answer has change to ,,We are considering many offers. You may certainly add your name to the list".
I hope that will help!
