I am guessing CEO was the first novel aimed toward female that she had read. In the end though both those aimed at males and aimed at female are pretty much the same shit.
On one side you have male MC who are often pill refiner and beautiful girls that fall in love with the MC left and right without any good reasons most of the times.
On the other side you have female MC who are often doctor and handsome guys fall in love with the MC left and right without any good reasons most of the times.
Other than those small difference most of the times novel aimed at males or female are more or less pretty much copy & paste of each other.
