There's one thing I don't like about Japanese reincarnations. Its when they make the past life "stronger" than the current life. Yeah, the past life has more memories (and more information to, thanks to all the media and education), but the feelings shouldn't be as strong.
Since she's lived like what? 18 years in this life, and 24 in the other, the personality of her current life should be a bit less strong in determining her beliefs and actions compared to her past life. But they always make it so that the personality of the old life completely rewrites the current life, to the point you might as well make it a posession instead of a reincarnation, if her experiences, thoughts, beliefs in the current life won't affect her.
