The premise of Obsession being a girl fall madly in love with a character she previously had zero interest after injesting/being under a spell has already be done in many media and, most of them, treat the situation in comedic sense. The character being subjugated by all this sudden love is often confused by it because it comes from nowhere and/or its totally out of character of her. They are worried and weirded out because its not a normal situation.
Bear made it a horror movie.
