I'm pretty sure 'Love Bite' is one of those vampire romance web novels that's gotten a decent following on the usual serial platforms. The main cast revolves around Elara, the human lead who's got that classic 'unaware of the supernatural world' vibe but with a backbone. She gets pulled into everything after a mysterious bite.
Then there's Kaelen, the vampire love interest who's centuries old and gives off major broody, protector energy. He's the one who bit her, but of course it's framed as this tragic accident or a moment of lost control, setting up the whole forbidden romance dynamic. They're your central pair.
You also have Lucian, who acts as the antagonist or rival—often another vampire from a different clan or with opposing goals, causing friction and raising the stakes. Completing the core group is usually a human best friend for Elara, like Sophie, who provides the normal-world perspective and comic relief. The roles are pretty standard for the genre: the innocent drawn into darkness, the tormented immortal, the external threat, and the grounding sidekick. It hits all the expected beats, which is fine if you're in the mood for exactly that.
