caremel if you want a reference for romance:
Actual romance from decent male perspective as well(without fillers but only 4-5 chaps. Short novel)- mulberry song, our second young master
In standard xianxia/wuxia(from male perspective)- i would say novels like martial art master has more realistic romance.
In xianxia/wuxia(female perspective)- romance and plot execution in novels like the road to jianghu is curved would be better. This is because such genres should not have all romance. But you can also write novels like 'seven unfortunate lifetimes'.
Modern world- good morning miss ghost, or perhaps something like i heard you like me too.
