The Little Princess Switched at Birth in a Male-Oriented Novel [Book Transmigration]

Vibia transmigrates into a male-oriented novel called Interstellar Magic Showdown, becoming the imperial princess who takes the male lead's place. ...Yes, she takes the male lead's place. As the evil villain everyone in the story wants to punish, Vibia decides to be a decent person and avoid the original's fate: being disowned by her family, condemned by the presiding judge, hunted by the Church, and pursued by the protagonist. She hopes that, once everything comes to light, she can retreat quietly into a monastery with relatively comfortable conditions. Instead, she accidentally turns the key characters who originally clashed with her into childhood friends, one boy and one girl. Vibia calmly says, "Since things have come to this, I've reflected on it. I think the key issue is that male-oriented novels usually run to a million words or more. When you're speed-reading, it's genuinely easy to overlook the little details tucked away in some obscure corner." A note for readers: An interstellar magic setting. Every worldbuilding element serves the plot. The heroine has a golden finger: a bound game System that allows her to draw prizes but does not let her pay for them. Theme: Study hard and strive for self-improvement.
