Is this good?
Yes and no. The story and plot is good but it drags out the story and if you hate harems then you probably shouldn't read this.
I'm honestly still reading cause of the mystery plot but if i knew it was harem i wouldn't have started it.
Sometimes the story feels like it's forgetting the plot then it remembers and returns to the story
Is this.... ghost harem?
Yes unfortunately
I believe the preferred term is “Boo Babes”
I love how just as i was about to drop this for turning into.harem garbage the author suddenly remembered the plot of the story and made it relevant again
