What happens with Duke girlfriend? is she die ? Melin have same hair colors with the duke girlfriend, Her Golden eye also similar with the duke...
So, duke girlfriend is the current saintess, and she's missing. My feeling the duke girlfriend is die when giving a birth to melin
I don't know if she could be missing her whole life without him noticing but she could be the mom and gave her away to protect her then since died
Readers predicted her parents is The Duke and saintess Verna. Even the duke aunt (Empress) ask him about melin identity because melin FACE and HAIR looks exactly like Verna, and empress also point out that "GOLDEN EYE" are uncommon in the empire.
