This has been an interesting read so far! Imma start it by saying if you're looking for some reverse harem/polyandry story, you should give this a try.
For one, it combined popular ML tropes (system, adventure) and using it to create a unique FL story.
My only gripe is the lack of tension or emotion buildup leading up to some major decisions (leaving home, creating a harem) and the snusnu part.
Anyway, this was an overall an enjoyable read. Definitely try if you're into Reverse Harems!
