Angel and Buffy, “Buffy The Vampire Slayer”
Honestly worse than “Twilight,” the Buffy and Angel relationship was sadistic and twisted. Buffy fell in love with Angel, and after sleeping with him on her 17th birthday, he returned to Angelus. He killed people to punish her for causing him to feel this way, taunted her and her friends. Not to mention that he also pulled the card of watching her in her sleep.
