The music video starts with a woman getting ready, putting on red lipstick or something like that. Then she's having a date with a guy who she ends up killing by drugging him or something like that. She gives him roofed wine or something. Then she kills him and dates, I think, two more guys, or one, and ends up killing them too.
At the end of the video she is standing behind their bodies, which are placed on chairs or something. It's a music video, somewhat like American Psycho I guess. The woman herself is pretty and has dark hair that, I believe, she puts up.
The tune is catchy and soft, I think, but I know it's a woman singing. I think she's singing anout Knowing something or Love. I honestly can't remember.
