This was nice. Quick and interesting. I liked the plot wasn't stretched that much. I loved their romance. Especially younger Khalid and his cute antics. Loved Ilya as strong minded Omega Empress. Though there's one thing that bothered me a lot that Khalid didn't rip the head of the men who touched his Omega. Apart from that the story is a good read. The translation though... it's low quality. I wish there was a better translation of this.
Kouguu no Omega
