Shirayuki and Zen Wistalia have officially declared their love for each other, and now everyone is going about their daily lives. At the royal palace of Clarines, Shirayuki continues to work as an apprentice court herbalist while Zen carries out his duties alongside his aides. However, their routines are disrupted when Crown Prince Izana receives an invitation from Raji Shenazard, the prince of Tanbarun. As a result, Shirayuki is ordered to travel to Tanbarun for seven days in order to establish a new friendship with the former self-centered and arrogant ruler who once attempted to make her his concubine. During this journey, she will inevitably encounter trouble again when she comes across a mysterious boy named Kazuki, someone she has never met before.
