Rebekah loves you but you aren't a vampire and she can't control herself around you any longer
"Look at me Y/N, im a monster and i can kill you in an instant, why aren't you scared!" Rebekah says getting fustrated
"Because i love you for you, no matter how old, human or vampire, i love you Rebekah Mikaelson and nothings going to change that" you say and she changes back to her human form, you intwine in a kiss
"Thank you Y/N" she whispers into your ear and you smile
