Intrepid traveler Shin has been to practically every country on the world map, except for the blank space around 500 kilometers away from his homeland. However, the moment he takes a single step forward, he's immediately captured and told that anyone who comes to Oraie can never leave. As Shin carves out a place for himself in Oraie, he gets to know more about its young leader Musutia, who bears the responsibility for Oraie's fate and future on his frail shoulders. He also meets Musutia's beautiful retainer Noe, whose duties often entail giving Musutia a "healing kiss." But is this just a ritual between master and servant? Or is there potential for it to blossom into anything more? (Source: futekiya) *Note: Includes two extra chapters.*

Shin, the third-born prince of the great kingdom of Garche, has lived with his servant Liandros since he was born... and now, Liandros has disappeared. Lia remained loyal despite Shin's "adventures" around the world and all the trouble he'd gotten them in. Unexpectedly shaken by this turn of events, Shin tracks Lia down to the small village of Barako on the fringes of Garche, where ancient religious structures still stand. There, he finds that Lia is receiving some sort of treatment from a suspicious so-called "shaman," and refuses to come home. That's when Shin starts to come down with a mysterious disease specific to the region... This is a story of deep, intense, and eternal love between a reckless prince and his loyal servant.
