Whoops forgot to post the rest LOL
You missed your opportunity. You let another guy lead her away. She seemed to feel safe comfortable and connected with you but you didn’t make your move. The drug she took played its part and that other a-hole that gave it to her took advantage of that. Its probably why he gave it to her to begin with. Leaving your target unattended is not a good thing until you establish something more concrete.
When you went to talk to the DJ you should have led her over there with you. I am border line on whether you should have stopped the guy. Drugs were involved so you dont know his state.
Pheromone could help a little but you would still have to take the lead.
