I'm playing Fallout 4, and I maxed out Affection with Piper, and got her perk. She frequently repeats the last bit that lets me try to choose Romance, but always shoots it down. I have max Charisma (with additional gear boosts), pretty good Luck, and she adores me.
Is it just random, and eventually should work, or did I do something wrong, and it just wants to keep reminding me? I managed it with three other Followers, no problems, but Piper is being uniquely challenging, and I'm not sure if there is a reason. Is it Piper-specific?
