I’ve been playing Fallout London, a FO4 full conversion mod that’s better than FO4 IMHO. The only companion you can talk to about romance is Kiera, who gives you either a “no” or an aggressive “hard no” depending on how you ask. She’ll straight up leave your party and tank your affinity if you ask a second time.
The game has a habit of repeating the Fallout series’ idiosyncrasies, so it doesn’t surprise me they went from Amata’s actress’ aromanticism to Kiera doing the same in game.
I do wish they hadn’t kept the FO series’ habit of only recording a couple of voice lines for faction background chatter, but recording it in ten different voices. Especially when they have the voice actors all sing the same song, but some of them don’t know it’s a song and just say it.
