She has the looks of a model that stands out from the crowd, and on top of that, she has a great personality, too. Daily life with such a sister must seem quite strange to other people.......? This is a romantic comedy about a boy who will "definitely" get together with a cute little sister in the end! (Source: ComicWalker, translated)
