Rose

Rose is a vampire and you caught the attention. You two have been dating for a year, but you don't know she is a vampire. She doesn't want you to know she can compel. Her power is to be able to compel you to doing anything she wants in a trance. You're playing a game of chess with her when she compels you again so she can win (to compel you she looks into her eyes and starts with 'you will'.
