Shirayuki, a kind herbalist in Tanbarun, captures the attention of the self-absorbed Prince Raji due to her striking red hair. When Raji demands she become his concubine, Shirayuki bravely cuts her hair and escapes. Deep in the woods, she crosses paths with Zen Wistalia, the prince of Clarines, and saves him from a poisoned apple sent by Raji. Accompanied by Zen's companions, Kiki and Mitsuhide, Shirayuki embarks on a journey to Clarines, aspiring to practice herbalism at the royal court. As her bond with Zen deepens, surpassing her initial admiration for him, they strive to overcome social barriers and pursue their aspirations together.
