The boy with the other face was the Duke. The pretty boy is the younger brother of the Duke and his name is Sati. It seems that the Duke uses the name of his yonuger brother, after killing him.

Gumina was engaged (and in love) with Sati (the younger brother). Due to the spell, she thinks the Duke is Sati.
