No - according to the novel (you can find the fan-made translation on MTL Corner https://mtlcorner.com/the-way-to-protect-the-f-emale-leads-older-brother/ ), she'll convince her father that the Cassis they see at the banquet is actually a doll/puppet created by Noel (the head of the Veritium of Gold family)... then she plays mind games with her father so he thinks that Noel is aligning with Pedalian of the Blue. She's playing 4D chess while her dad is playing tic-tac-toe! XD
I am so excited to see Roxy play more 4d chess thank you
What chapter in the novel is it?
Chapter 59-60
But if Cassis appears just like that, Roxanne's dad will know she didn't kill him that day and she betrayed the family by letting him escape instead. Wouldn't she be in danger?
