Despite a strong desire to become an ordinary human, which could make it possible, when his child wasn't in love with anyone, naturally, they wouldn't have such a strong desire to be ordinary, and thus, half-human, half-mermaid creatures living in the human world are truly pitiful! Moreover, for a mermaid, becoming an ordinary human and giving up on youth and immortality is undoubtedly tantamount to giving up their own life.
Both humans and the Mermaid Clan wouldn't consider those offspring from the union of mermaids and humans as their own.
Being born on land from the start, living alone at the bottom of the sea would be very lonely, and even if they found the Mermaid Clan, it's not certain they would accept a child born from a mermaid and a human!
