The psychological eroticism in Nana's and nanao's relationship is top tier in a shounen series that is the 1% of female agency while not making said female the love interest cheerleader( that only exist as the love interest of the male mc and thats the female characters only trait) that makes 99% of shounen series
The fact that their relationship is 5% of the series is a master-class that female characters can have romance that is 5% of the story yet 2000% in execution
