It is Harem, the love interest is Hekate the princess (they got engaged) but other 2 girls also like him (Elf and Beast King-female). The Elf is kinda okay (calm, elegant, useful -still I wish he only end up with the princess).
But the Beast King is just agly, loud, old, only brute strength. Even his master more beautiful and elegant (or he might as well choose white tower master and the other princess). So yeah the harem members are annoying loud cringe no brainer.

Wait.... this is harem?? NOOOOOO I'd rather this have no romance in the first place but harem?? I only reached chapter 57 and it's such a good story but after looking at the comments, it's not just romance but harem?? The author is ruining a very good story. I think I'll drop
