Hi, I'm a new reader, and I'm loving your novel so far. The world-building is phenomenal and it nice to read a story where the main pairing is loyal and actually communicates with each other. This is the best novel I've read in months and I'm glad you decided to share this story with us.
Just in case in gets lost in the weeds, I'll repost it here:
You absolutely should get rid of the chapters that weren't as you originally intended. Changing your story for any reason other than it not working for your intentions (or obligations, if you're being paid for) as written is one of the worst things you can do.
