| Heir to the Duchy of Sudbury|
|Hair color:||Hot Pink|
Lady Gwenelle of Sudbury is a schoolmate and friend of Elodie's who, as a young heiress, is in a situation parallel to hers. Her father is dead and when she reaches her fifteenth birthday (Week 28) she will inherit control of Sudbury duchy. Her mother, Lieke, wishes to remain her close advisor, but Gwenelle thinks of herself as an adult and prefers to be an independent ruler. When Elodie mediates this dispute in Gwenelle's fifteenth birthday party, it reflects her own tendency to be willful or yielding with respect to her father's advice.
She's also mentioned if Elodie chooses to marry Anciet. While the idea of marriage starts as a joke between friends, Anciet grows to fall for Elodie, and she eventually reciprocates. It's mentioned that both had a hard time convincing Gwenelle that their wedding wasn't a joke as well.
- She was a baby when Lieke married Bennett. As a result he was responsible for raising Gwenelle, and in turn she considers Bennett her real father.
