I need help...

[Lauren (aplpeach)]

I am trying to find a book, but I can't really remember what it is about. All I can remember is that the male lead talks to his sister and she tells him that the more adventurous she is the more loving, and caring he has to be towards her after. Can anyone help me please?

I picked this book to post this in, because it is close to what I am looking for, or the book I am looking for.
