Kimi o Matsu -> Akaiito

From Dazzling Scans: Matsuri had always been victimized and bullied because of her bright red hair. One day, two brothers, Natsume Fuuzou and Tsukuya, are hired to work at her family's bed and breakfast. It seems they have run away from home and are trying to earn their way in the world. However, there might be more to them that meets the eye... especially the strong, silent Tsukuya who manages to look past Matsuri's red hair and see her for who she really is.
