The villain in this world was Oliver, an Omega prince of the Alaze Kingdom. Upon birth, he showed signs of fragile health and compared to his half siblings who at least had prominent beast marks, he only had slightly unusual slit eyes which wouldn't be noticeable unless one looked at him closely. That was also why he was deemed unfavourable. The Emperor came to see him only once when he had just been born and his siblings mocked him for looking like a human despite being a royalty.
