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.

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.
