The original story of this drama is based on the immortal bestseller "Little Women" by American writer Louisa May Alcott. Starting from the idea of "what if those four sisters lived in Reiwa Japan", the stage is boldly replaced to describe the social comedy of sisters in the modern era. The four sisters of the Machida family live tenaciously and noisily under the same roof. When they encounter unavoidable life problems such as work, love, marriage, and dreams, the four sisters continue to try and fail, exploring their own happiness.
