Why is Azriel so popular as a personal romance pick for so many people??

I’ve noticed most people I talk to have a personal crush on Azriel and I’m sort of confused about why? We know little to nothing about him, we’ve seen basically none of his personality, and honestly if he wasn’t IC I’d be suspicious of if he was even a good person. For the last point I feel this way because his ability to sit in silence and stair and buildings waiting for any sign of movement (his spying) is downright serial killer behavior. He is known for his incredible ability to torture people??? And is generally quiet/standoffish in nature. So I’m genuinely wondering why people like him? Not even judging at all because these are fictional people like who cares who likes who lol and I’m sure Az is super hot physically but I genuinely want your guys takes on it or if anyone agrees with me on this lol. Like who is Azriel and why is everyone so hot and bothered about him😂
