The woman, the wife has the child and it is a baby boy. The baby boy grows up in the human realm with his mother with his elf ears and magic suppressed and locked away inside of him. The King has a son warrior and the King sent him to the human realm to find the cursed child and kill him,as the truth was revealed eventually and the man ("evil" child's father) was put in prison for lying to the kingdom.

The son goes to the human realm in search of this cursed child. After a while as they ventured into a forest, unexpectedly they bump into each other and the boy is hurt and the prince uses his healing magic to heal him and he reveals himself. The boy eventually finds out who he is as his magic seal suppressing his magic was busted by the healing and his magic that has been suppressed has built up over time and it's now all just one big burst of magic catching the attention of the elven kingdom.

The boy's mother confesses and tells the boy the truth about who he is and offers to have an old friend train him to take better control over his magic. The prince eventually becomes suspicious of the boy and wonders why he can do something he can do because he secretly uses his magic in his daily life as he learns to control it.
