Tsuki to Yabanjin and Ouji to Kotori both explore the basic premise of a foreigner getting lost/trapped in an Arabian desert, where upon they are taken under the protection of a Arabian prince. The characters are also alike, with the ukes in both stories being physically weak, and of a kind and resilient nature (i.e. very cute), and the semes being dominant, intelligent and noble (i.e. very sexy). In regard to story lines, the mangas differ quite distinctly, but both present plots that are interesting and well-thought out. Personally, I prefer Ouji because the plot involved some dark concepts, which I love (in comparison, Tsuki is quite a fluffy manga). Overall though, both manga fulfilled that craving for an exotic and slightly forbidden romance!  read more
Both short volumes share an almost fantastical love story between two men of either different races (Tsuki to Yabanjin) or of different social classes (Taiyou no Kikoushi). The main leads share common aspects to their personalities such as the semes are bold and are accustomed to getting exactly what they want while the ukes have shy but strong personalities that puzzle and intrigue their partners.
In my personal opinion, I like Taiyou better because I can connect better with the uke since he has grown because of all the failures in his life. But, please read both. Both stories give a lovely atmosphere that you'll be lost in and be begging for more even as you turn the last few pages. read more
