This was interesting purely for the plot of being with the person you are genuinely attracted to or leaving them to be with your fated pair, which you have no choice over. I really liked how this manga explored that and how it dealt with it. Was it perfect? No. But it did open up a door for other stories to take this route, I look forward to finding them. I only wish we had seen more of Kaoru and Yuka's romantic relationship.
