Prince Blueblood is the most eligible stallion in Equestria. All the mares know it (as do a measureable percentage of the other stallions, but that's not exactly a problem). The problem is, Blueblood knows it as well, which is why he's decided to be the perfect boor at social events, under the assumption that only the most worthy mare would trouble herself with his loutish behavior and prove herself worthy of his attention, affection, and sizeable fortune.

It wasn't a particularly good decision, but then again, he was raised to be Eligible, Handsome, and Intelligent, but not Wise, which is why our story begins in the aftermath of a Particular Grand Galloping Gala, wherein our frosting-covered hero sets his first hoof on a path that, if he's very, very lucky, might see him imprisoned for life married.

No matter what happens, he is, most likely, doomed.
