This was such an interesting take on the Reincarnated Villainess genre. I love how the "target" was the main narrator, and the reincarnated villainess was just a clumsy girl with a heart of gold. When the "reincarnators" usually get into the world, they're usually very competent at successfully changing the story and using their knowledge of the story/game to their advantage. I liked how with Bertia, she had no idea how to use her knowledge to change the story, kinda like a normal girl. Yeah, she's as dense as a collapsing star, but it is a part of her charm. The Prince was absolutely the best part of the whole story. I loved how he was written. The story has some rather dark moments which is really nice. The art style is beautiful and very expressive. All-around very good story. 10/10 for me.
