First theory:
I think Philomel is the Blondie in the past and the Blondie was Philomel in the past. I think they switched. So the past Philomel wants to have her father's love and everything that past Blondie have.
Second theory:
Philomel is Philomel from the past but the Blondie in this life is maybe a transmigrator, who read the book Philomel read in ch. 1.
Third theory:(Least likely)
They both got reincarnated, Philomel read a book about her previous life but the blondie just has the past memories.
Either way, Blondie in the present is an attention wh*re who is giving a lot of red flags, and I can't wait for when her fake a** mask gets yanked out and everyone finds out who she really is.
