Sanbyoushi no Musume

They've been abandoned by their parents, but they're still living quite happily. The three Orihara sisters are Sumi, the easy-going eldest daughter, Tora, the free-spirited middle daughter, and Fuji, the smart but mysterious third daughter. They may not be perfect, but they live life to their own rhythm. As light as a waltz, their daily life is strong, fun, and lovely. (Source: eBookJapan, translated)
