Huh, I rated this in the past, and I think it's still true:
I'm conflicted about this one. It's not the worst of the set by a long short, but it also doesn't really satisfy in the same way as some of the better ones. I think it's solidly in the middle of the collection for me.
That being said, I've had more time to muse on this, and a part of the reason why this feels awkward goes to that copy-paste again:
I think it's also ... a common trope I dislike in these - it's a story where a 'princess' does little and gets swept off her feet by someone else solving the problem in the name of love. Sound familiar? Since that's probably one of the most common clichés around, so if you want to do that story, you have to do it very well..
This is a more interesting twist on that, since it involves the villainess summoning a demon to kick it off, which makes it a little more unique and makes the 'villainess' side click. It goes a step further in pointing out how messed up it is to pursue love while being in another active relationship, so those are points in its favor. However, it's awkward that the only reason those themes are viable here is because the person with the bigger mind-controlling stick says so.
I think that continues to put this in the middle of the pack - good enough to be interesting, but not compelling due to how many shortcuts it takes to get that final message across.
