I Won't Marry the Prince, I'll Win Over the World's Greatest Man

A Refined, Noble Gentleman of a Male Lead (He Can Be Unhinged, but Not Insane)

This is exactly my thing, but I still haven't found one I like. Any platform is fine, just say where it's from. Cultivation or fantasy, no CP is preferred. Romance is okay too, but if it's from the female lead's perspective, the male lead needs to have a strong character of his own, not just exist to support the female lead or whatever.
