I think you're on to something. I do like Yona, but she and Blair are still in the last couple among the House girls. Rae is a "perfect waifu" type so she's impossible to dislike, Cait and Lyriel have personalities that aren't nearly as engaging as Rae's but I'm a sucker for the slender schoolgirl figures, and Naomi is less attractive to me but charismatic enough that I still like her. Blair's dumpy physique and off-putting personality don't do it for me, and Yona is sweet enough but a muscle-bound woman with pig tusks just doesn't scream "sexy" to me.
