This was an interesting read! I liked the bareboned look of the characters and the ideas that were brought forth in the story.
I think given a month or 2 more this could have been a really good story! I think it fell flat in some places personally, like how the cabin was there and just so happened to have things they needed for the night, we didn't get much more worldbuilding on the curse except that it had been spreading around the kingdom and the king has been ignoring it, and we never learned what the voice was that was speaking to the mc's mind.
I also felt like the relationship with the main two had no substance behind it, besides being a long-distance crush and being saved by them. And then at the end declaring their love for each other, despite having only spent one night together. Please don't take this the wrong way, but this feels a bit stockholm syndromey. It probably only feels that way because of how fast paced the story got at the latter half, and how you probably ran out of time, so you wanted to finish the story with the finale you had planned before.
All-in-all though, Great job!
