Let me guess, MC gets isekaied as an "otome game villainess" except that she is a 10/10 good girl with no flaws. Due to the otome game plot, perfect men with no or minor flaws keep knocking on her door no matter what she does to avoid them. Even if she gets banished, she can lead a perfect, comfortable life without needing to worry about money, falling sick or any other issues. She never has to learn or do anything difficult and the series completely skips over her learning all the stuff that noblewomen are expected to learn such as etiquette. If she doesnt get banished, she basically just gets pampered with lots of money and servants with the "plot" basically being "scene from otome game and MC's reaction to it".
How close am I?
