Hanayaka Nari, Waga Ichizoku

When her father falls ill, Asagi Haru must support her family. She quits her factory job and starts searching for new work. That's when she runs into Egawa Chitomi and Arita Kisuke, who are looking for a maid for the Miyanomori family. On the spot, Haru applies for the position, leaving her hometown to work at their mansion in Tokyo. She thought being a maid would be fun until she meets the six Miyanomori brothers. Each brother has a different mother, all divorced from their father, the family head, Miyanomori Genichirou. Growing up in a big family, most of the brothers treat Haru like dirt, calling her trash and seeing her as a lowly servant with no right to speak back. Not to mention, her new tsundere friend Tae keeps lying and getting her into trouble. Haru quickly realizes that her new job is far from easy, but she must work hard for her family's sake. Soon after Haru starts, Genichirou announces his retirement and a game to decide the next head: the brothers must entertain him and collect points. The first to reach ten points becomes the new head, and they have until March to please him. This is why the brothers all have different mothers—Genichirou wants to pit them in a battle for succession. (From Love-colored Sky)
