The pseudo science is the level of detail you went into to mock stormzy looks. I don’t think that’s how real life attraction works
I am not a women, but I don’t think most women would see stormzy as one of the ugliest people walking around, which is the impression you gave with your scientific autopsy of his face. He walks into a room in his late teens as a 6ft 5(?) 85kg muscular young black man from South London, I think he has a lot going for him. There is more nuance to what women find attractive than some what nerds from Harvard wrote.
Maya wasn’t that famous at the time as well, so he wasn’t exactly competing with A list celebrities to get her. The aspiring rapper, slash drug dealer vibe does carry some privilege in some communities as well. I know some middle class white girls who cheated on their successful boyfriends for some action from the 50 cent types. There are girls from posh unis hopping on trains to meet up with some random Jamaican and Somali drug dealers in London.
I don’t see what’s so surprising that Maya, in her early days, got with an aspiring rapper who was known around London in the grime scene and she was also from a similar background? If she started a relationship with Delroy from the job centre, now that would be a story.
