One common theme is friendship. The relationship between the three characters can be explored in terms of how they become friends, support each other, and have fun together. Another theme could be cultural exchange, since Spain and Romano have their own distinct cultures in the Hetalia universe, and the reader can be a part of that exchange.
A theme that is sometimes seen is historical or cultural references. Given that Hetalia is based on personifying countries, fanfictions in this pairing might incorporate real - life historical events or cultural traditions. For example, they could reference Spanish festivals or Italian cuisine. This not only adds depth to the story but also helps to immerse the reader in the world of the fanfiction and understand the characters better through their cultural backgrounds.
A great Romano x Reader x Spain fanfiction needs to capture the essence of the characters. Romano is known for his love of tomatoes and his pride in his heritage. Spain has his love for his country and his more carefree attitude. When the writer incorporates these traits into the story, it feels more authentic. Also, the relationship dynamics are important. The Reader should not be just a passive character but have their own agency. They could be the one who brings Romano and Spain closer or causes some drama between them. The story should also have a good pacing, not too rushed or too slow, so that the reader can fully immerse themselves in the world of the fanfiction.

Given that Romano and Spain have different cultural backgrounds in the Hetalia universe, the crossdress aspect might add an interesting layer to how they interact culturally. For example, how Romano's perception of Spanish culture changes while in crossdress.
One common theme is the struggle between two very different forms of love. Italy might represent a gentle, affectionate love, while Romano could be a more intense, possessive kind.

One common theme is cultural exchange. Since Spain and Romano (presumably representing Italy) have different cultures, the fanfic might explore how they share and learn from each other's traditions.

In 'italy x reader x romano lemon fanfiction', one common theme is passion. Given the nature of the 'lemon' aspect, which often implies a more intense, physical relationship, passion is likely to be a central theme. Also, family influence can be a theme.
