Eric & Sookie

Eric Northman and Sookie Stackhouse are characters from the TV series True Blood, which is based on the Southern Vampire Mysteries/Sookie Stackhouse book series by Charlaine Harris.

Sookie is a human/fairy hybrid living in Bon Temps, Louisiana, and works as a waitress at Merlotte's. She has the ability to hear people's thoughts, and being part fairy she also has other abilities like photokinesis.
Eric is the vampire sheriff of Area 5 in Louisiana which encompasses Bon Temps. He was born in Sweden during the Viking age, making him over 1,100 years old. He owns the vampire bar Fangtasia in Shreveport, Louisiana.
Eric and Sookie first met in the fourth episode of season one titled "Escape from Dragon House".

Eric has not demonstrated the outward concern for Sookie that he exhibited in the early novels, but he appears to be developing an uneasy, guarded affection for her and the series seems to portray a reluctance on his part to show people, particularly Sookie, his genuine emotions. Often Eric has presented himself to Sookie as violent, arrogant, mischievous and consciously manipulative. Thus far in the series he has usually acted in a manner with little apparent concern for Sookie's feelings or immediate safety, although ultimately he seems to protect her.
However, his growing feelings for Sookie are showcased in episode 4 of season 3 when he daydreams about Sookie. In episode 10, Eric kissed Sookie, after proclaiming that if he were to die a true death without having at least kissed her, that would be his greatest regret. He chained her up in his basement a few minutes later as bait for Russell. He again reveals his guarded affection for her when prompted by Russell to drink her blood, he hesitates and strokes her affectionately on the cheek. Finally, in the season three finale, he tells her that he regrets seeing her in such pain, referring to her heartbreak over ending her relationship with Bill.
