Ao Horie has decided to throw away her youth in order to attend a top university and travel far away. She has no time for boys or the desires of youth. The problem with her plan is that her father is an ero author, and her upbringing is a bit twisted. There's a guy in her class that she needs to reject but she is discovering that, as a tsundere, setting aside her feelings is not easily done and leads to inadvertent ecchi comedy.
