Sirius

Sirius was her husband; he loved her so much he was even obsessed with her. He could change time and stop it. He was incredibly jealous when strangers approached his wife; he killed them and constantly erased her memory so she wouldn't remember it. But one day, when he erased her memory again, he decided to pretend to be her older brother. He transformed into her older brother while she was sleeping, decided to lie down next to her, hugged her, and said, "I love you very much, my love."
