Often, there's a protector - protectee dynamic in a 'sonamy vampire love story'. If Sonic is the vampire, he may struggle with his dark urges while trying to protect Amy from the other vampires or from the harm his own nature could cause her. On the other hand, if Amy is the vampire, Sonic may have to protect her from those who would hunt her down. And of course, there's the love that blossoms in the midst of all this chaos. Their love is what gives them the strength to face the many difficulties that come with the vampire - filled world, such as dealing with ancient vampire curses or facing off against powerful vampire lords.
One common plot element is the forbidden love aspect. Since Sonic is a heroic character and Amy is often seen as a more innocent type, the vampire theme adds a layer of danger and forbiddenness to their relationship. Another element could be the struggle with identity. If Sonic or Amy were to become a vampire, they would have to deal with a new identity and how it affects their relationship.
In a 'sonamy vampire love story', a typical plot element is the discovery of the vampire world. Maybe Amy stumbles upon a hidden vampire lair or Sonic gets bitten by a vampire. This leads to a series of events where they have to learn about the vampire lore, like how to control bloodlust or deal with vampire hunters. Also, there's often a lot of tension between their normal lives and this new, dangerous world they've entered. Their love has to survive through all these challenges, including the possibility of one of them being turned into a vampire against their will, which would change the dynamics of their relationship forever.
