Please recommend me some book series with a male lead like Nikolai Lantsov from Grishaverse

So I’m looking for books (but finished series preferably), romantasy preferably too, with a male lead like him – cunning, charismatic and charming but also smart and having some good backstory behind too, holding some sort of power. And please if a female lead wouldn’t be bland and having no character like Bella Swan too 😭
