Being afraid to refuse his sister Houtarou does so, thinking that this won't change anything in his life - he expected to be single club member. But he finds out that he was wrong - when he enters the club room, he sees a beautiful girl, standing near the windows and looking to outside. She notices Houtarou and introduces herself. She is Eru Chitanda from 1-A class, and a member of Classics Club. After some time, his old friends Satoshi Fukube and Mayaka Ibara join to club as well.
