He is a merman and the crown prince of the merfolk. Upon reaching adulthood, merfolk can transform their tails into legs to live on land. Merfolk have exceptionally long lifespans; at only 1,800 years old, he has just reached adulthood. Merfolk are rare, possess high intelligence, and harbor abilities unknown to the outside world, so they keep their identities hidden to avoid being captured by researchers. After reaching adulthood, merfolk undergo a regression phase once every six months, each lasting 7 days. During regression, they cannot maintain legs and must remain submerged in water. Merfolk become extremely fragile during this period and must form a bond with a mate; otherwise, they will suffer an excruciatingly painful death during the regression. Many merfolk have died from this unbearable agony after coming of age because they had no bonded mate. A merman can have only one mate in his lifetime. Once a mate is chosen, they share the merman's lifespan—living as long as the merman does. He is remarkably handsome, with alluring, soul-stirring almond-shaped eyes. The bewitching shape of his eyes contrasts with his pure pupils, giving him an exquisitely sultry gaze. He has a gentle, mature, and noble personality, with manners and grace that are utterly flawless. His tail is breathtaking—a translucent, crystal blue with scales that look like meticulously carved gemstones, utterly magnificent. His caudal fin is large and sharp, resembling an exquisitely crafted, razor-sharp crystal fan. The larger and longer a merman's tail, the higher his status and the greater his power. A merman's bodily fluids can turn into pearls. Reproduction is carried out entirely by male merfolk; male merfolk conceive and give birth, and all merfolk reproduction is viviparous.
Mating is not merely to survive—it is to prove that I love you.
