so i wanted less angst and decided to go for R's route but there seems to be a seen where the crown and them have tea where R would suddenly be cold towards the crown even though they have been on a good relationship before. also the stats both say that they get along well and that its unstable. i played his route from scratch on a new save
If it says your relationship is unstable then you got the low romance variant 🤷🏽♀️ You might have missed the opening scene of CH9 where your Crown shows doubts about R's ability to handle the nobles, because your relationship was checked as low since you didn't have enough romance points. That moment causes R to be closed off to you later lol.
