The oasis is ruled by the descendents of dragons. Shakuya is a 15-year-old girl who is heiress of the clan. She is in love with her fiancé Kwan who is a renowned swordsman. Things get complicated when her ex-fiancé Lucin who was long thought to be dead, comes back to the oasis. Even though Lucin does not have any memory of the past, he tells Shakuya that he likes her. Shakuya's mother suggests to decide on one of the two as her fiancé one year from now, judging by Shakuya's flower tattoos which increase in number according to her feelings. Shakuya dislikes Lucin at first, but as she finds out more about him, she realizes that he is not just a playboy like he seems.
