Shirayuki is a normal herbalist in the kingdom of Tanbarun with one unique feature: her beautiful red hair which attracts a lot of attention. Due to her unusual hair color, Shirayuki was raised to always be careful of showing her hair in new surroundings, tying it up with a red ribbon and grew to be an independent, young woman. However, her hair gets her noticed by Prince Raj, who orders her to become his concubine. Refusing his orders, she cuts her hair and leaves it behind, as she knew that he only wanted her for her unique hair color and escapes to the neighboring kingdom of Clarines. On her way there, she meets and befriends Prince Zen Wistaria and his two aides, Mitsuhide and Kiki. When Zen is poisoned by an apple meant for Shirayuki, gifted by Raj, she successfully obtains the antidote and decides to accompany the trio to Clarines. Shortly thereafter, Shirayuki passes an exam for a position to train in the palace as a royal court herbalist. Shirayuki finds a place in Clarines and carries out her duties as a court herbalist, befriending the youngest herbalist, Ryu. Prince Raj realizes his feeling towards Shirayuki and starts working hard to become an ideal prince for her. Over the course of the story, Zen and Shirayuki begin to fall in love with each other and eventually begin a romantic relationship, in spite of opposition due to their difference in social status.
