I have a DHV story that I've realized could be quite powerful, as well as a good female opinion question. However, its quite dark, and Im wondering when the right time to use it in an interaction would be, if I use it at all.

Basically, I was staying with my best mates girlfriend (DHV, implies I'm trusted and loyal to friends) and we went out clubbing with a few of her friends (all girls.) At some point during the night, someone spiked her drink, and when she texted her friends to tell them that she thought this had happened (it was medically confirmed that she was) none of them paid any attention to her, and instead hung around with a group of guys they had met and hooked up with, and one of them even took a guy back to her house and slept with him in the spare room.
I looked after her for a while, and called her father and we got her home safely.

The next day, her friends were extremely apologetic about leaving her etc etc and the way I would phrase it if using it, would be, should she trust them and still hang out with them, or have they shown their true colors.

Now this could be a DHV in that it shows very clearly that I am a protector of loved ones, but seeing as the story is quite dark, it could very easily kill a playful mood and possibly bring up bad experiences from a girls past.
Anyone have a way that this story/opinion opener could be used successfully? I imagine during a comfort building phase, probably not as an opener as such, but more an opinion during a conversation.
The reason I realised it was such a good DHV, is that one of her friends, I had tried to go for several times during the night had soundly rebuffed me. But after this, she has been messaging me saying what an amazing guy I am, and how she really wants to see me again etc etc (which I dont, but I still realise that what I did was a DHV)

I also worry if using this story is almost a little unethical, and exploitative of the situation, and not something I should use in good conscience.
Any thoughts?

Interesting idea, recon it's a little dark imo but It all really depends on delivery, you can say pretty much anything as long as you say it in the right way, and get away with it. Your DHV will almost definitely get her attention, only problem being it kinda paints a negative image of blokes in the story.

Only one way to find out...

Yeah that's go over well, but only once you've been talking to a girl for a while. Once you're sharing details about family and other personal stuff, you're probably okay to slip that story in, depending on context.

I would say to calibrate it for individual girls, like maybe not say it to party girls, because it would strike close to home for them, but at the same time, it would make them see you in such a protective light. I can't think of any cases where a girl wouldn't like that story, it seems pretty universal.

And yeah, you're obviously a good guy, this is a great way to express it.

The problem with this story is people may interpret it the other way. Everyone is having a great time, girls are flirting with guys, hooking up, but you are stuck playing babysitter for your friends gf; weak - especially since you don't know about the roofie until after the fact.

To turn it into a "real" DHV story setup something like this

".... this one time we were at a club and my friend starts acting weird, she does x, y and z blah blah blah SHE's like a little sister to me so I end up taking her home. The next day we go to the doctors and she tested positive for xxx..... a date rape drug. (at this point they'll probably be wow or omg or thats awful) ya it's pretty crazy what people do nowadays, you see this stuff on the news but you never think about it till it hits home. "

set it up how you want and play around but make sure the punchline, the part about the roofie, is at the end. Leave out the other shit like her friends and what they are doing unless the people ask about it. This way it doesn't appear like your condencedning - I mean if you are taking care of her why would her friends need too as well?
