What if the ML doesn't like Blue Su Luxia when Purple Su Luxia moves on to the next mission? Will he just break it off with her and just keep it to a professional relationship? I'm asking because it seems like everytime Mr. Gu meets with the MC, she is possessed by Purple Su.
I think it is a kind of poison that only the royal family has and that they're doing it to get rid of her influential family. It could also be that her brother is in cahoots with the king or maybe colluding with the anti-Visaradae faction like that.
