Sorata Akizuki’s Snow White with the Red Hair (Akagami no Shirayukihime) is an ongoing shoujo manga. It is very, very, very loosely based on the folktale of Snow White.
Prince Raji of Tabarun decides to take herbalist Shirayuki as his next concubine. Why? Because her hair is the colour of red ripe apples. It does not occur to him that Shirayuki might have her own thoughts about the matter. He dispatches a summons and awaits his new red-haired lover.
Rather than submit to being a spoiled prince’s momentary pastime, Shirayuki cuts off her long red hair, leaving it for the prince who valued it so much, then decamps for the neighbouring kingdom of Clarines. Along the way she takes shelter in an abandoned mansion, one that is not so empty as it appears.
Enter another prince.
