If you liked the The Desert Prince manga, the Anime-Planet community thinks you'd like:
He’s the ruler of the country of Roinne; she’s a typical Korean teen, and his 100% perfect girl. For the rich and powerful Jarte, he wants nothing more than to take this girl, Jay, for his own, and together the two begin a tentative, tender relationship. However, Jay and Jarte’s lives will be nothing but simple, as insecurities, assassins and rivals in love stand in the way! Will the two manage to stay happy together?
Both of these manga are about foreign royalty who fall in love at first sight with commoners of other countries. Although one is a homosexual relationship both stories are very similar (although the plot of Perfect Girl keeps expanding), and if you loved one you might enjoy the other.
Kiyo Katsuragi has just arrived at a special mansion in a remote area of the mountains. Said to be haunted, it has been bequeathed to her by a late grandmother who she has never met. While she originally intended to demolish the house and sell the land to pay for college, Kiyo soon changes her mind after meeting the building's live-in tenants: Kuroboshi-sama and his servant Alushu - two vampires! As if dealing with two supernatural beings isn't strange enough, Kiyo soon finds herself deemed to be Kuroboshi's 'bride'. Now, in addition to working towards her dream of becoming a lawyer, Kiyo must handle Kuroboshi's overprotective nature and advances to drink her blood, while also coming to terms with her feelings for her new companion!
Although The Desert Prince is less innocent, both of these stories involve sexy men trying to flirt their way into the hearts of someone who resists. If you liked one (and don't mind shounen ai content) then you might enjoy the other.
In both of these series there is a powerful and wealthy male character who falls in love with someone they decide they *must* have. The plots revolve around them trying to make their 'true love' fall in love with them. If you enjoyed one, you'll like the other.
