I TAUGHT A SIREN TO LOVE, THEN BECAME HIS MATE2화

Mira Hale, a marine research grad student on planet Thalassa, mistakenly assumes a solitary, lethal Siren named Auren is just a courtship-clueless merman in need of dating lessons for her thesis. But when she performs the mating dance for him, the deep-sea predator claims her as his fated mate. Abducted to his underwater cave, Mira slowly uncovers forgotten childhood memories of the boy who saved her life and waited a decade for her return. Overcoming fear, distrust, and interspecies barriers, their fraught bond transforms into an unbreakable love that defies the entire galaxy.
