I Thought I Was Reincarnated As A Villainess, But It Was As Marie Antoinette

A "Christmas cake" office worker got pierced by an Eiffel Tower decoration, died, and got reincarnated as Marie Antoinette.

*"Christmas Cake" in this context is Japanese slang for a woman over 25 years old, as it's said that no one wants a Christmas Cake after the 25th.
