I think that at least for right now, he has feeling for all three of them, but I dont think its "fully realized" by him.  The girls sorta know they like him, but he more is "cloudy" on that. 

Its hard for me to word, but its not in the same way that other protags in a romance based story have the "confess you idiot" if that makes sense.  

For those curious:

Baobh-shìth are Scottish Gaelic Female Fae whose name roughly translate to "White Woman of the Scottish Highlands".  As the previous poster stated, they do have similar connotations as Succubi, but they also resemble in some forms Banshee and Vampires (insofar as they hunt and drink for blood).  They are very much attracted by the scent of blood.

Typically have deer hoves as feet and appearing in green clothing, like other fae who can glamour, they can take on other forms.  And like most fae of Gaelic lore, they are driven away by iron (Pokemon fans remember that Steel beats Fairy).  Which does beg the question of if someone has Hemochromotosis, could that drive one away?
