The Betrayed Demi-God Reclaims Everything

Sinopsis

After three years of fighting on the northern front, legendary dragon rider Kalen Gerard returns home, ready to marry the woman he has loved for years. Instead, he finds his castle occupied, his fiancée pregnant with another man's child, and his family legacy stolen by a shameless usurper.
Branded a worthless nobody, Kalen is ordered to give up his title, his home, and even raise his fiancée's illegitimate child. But no one knows the truth—he is the kingdom's greatest war hero, the man who slew the Black Dragon and saved humanity.
