The Siren Emperor's Pet

Elara, a low-born girl carrying a special beast-alluring bloodline, falls into the black market to save her brother and unexpectedly awakens Caspian, a cruel deep-sea monster emperor. Forcibly confined by him, she — with the chaebol hunting them crazily — and he move from prey and captor, through life-and-death battles, to break through the barrier of species and complete a mutual redemption.
