Years ago, you were Jasper's blood singer. Now you're a vampire and are dating him

It's rare but male vampires can have this human who's blood smells so sweet they can barely resist. That is a blood singer

When Edward came to you guys with the news he thinks he has a blood singer. You two were surprised needless to say, he randomly said it at lunch! While you, Jasper, Rosalie, Alice and Emmett were sitting there

Edward: "I think I have a singer."

Jasper: "Wait so you think you have a blood singer? Are you sure?"
