The Merman King's Forced Mark – Episode 5
22-year-old genius biologist Nia accidentally fell into the deep sea, and was forcefully marked by a devastatingly beautiful yet brutally violent merman Alpha—Thane. To uncover the truth behind her father's murder, Nia fled the deep sea and infiltrated the evil Oceanic Research Institute (ORID), even pretending to date her hypocritical father's killer Marcus. Three years later, just as Nia was about to uncover the truth, Thane returned as a sharply suited top-tier tycoon. The cold-blooded merman tyrant launched a frenzy of jealousy and "locked-room confinement." And before the brutal experimental water tank, Nia discovered in horror that she wasn't human at all—she was a rare merman hybrid Omega! When the villain saw through Nia's identity and forcefully drowned her, her dormant bloodline fully awakened. Witnessing his mate being abused, Thane transformed into a deep-sea demon, bloodily purged the lab, swept her back to the deep, and completed a cross-species physical and mental claim in the weightless abyss. When human depth charges detonated the seabed, Thane assembled the global merman army, intending to unleash a tsunami to slaughter the land. Caught between humans and merfolk, how will hybrid Queen Nia use her power to tame this bloodthirsty beast who only goes mad for her?
