Interesting Setting . It seems you aren't very knowledgeable about modern gadget to be talked about sci-fi world . Plus the grammar problem . Good luck

harem....that ain't necessary for all devils(but most or atleast that's what everyone wants you to believe to do so,you're just going along with the flow). I really don't understand why most novels are insistent on harem, I'm quite sure non harem lovers is not minority But thanks for not pretending like you didn't have a opinion towards harem/nonharem

One thing I don't like about this novel is how toxic Adrianna 's love is for family . I'd really like to know if she would stay with Cedric if she was asked to abandon her family without identity revelation
