Zekehart was shown to resent Cosette.
- In the first timeline, Zekehart first met Cosette at his 13th birthday banquet where she makes her appearance and was shocked by her presence.
- When Keira Parvis returned to the past after being executed for being the 'fake' daughter in the first timeline, Zekehart instantly grew to hate Cosette after she makes her debut at his 13th birthday banquet to the point that he tells Keira to "ignore her like she's a nobody! Then she won't be able to endure it and she'll leave!" in Chapter 40.
