Romance is also a big theme. The OC usually gets involved in a romantic relationship with one or more of the host club members. It could be a slow - burn romance or a love - at - first - sight kind of situation.
One common theme is the discovery of new sides of the characters. When a baby is introduced into the story, the hosts who are usually all about entertaining guests in a sophisticated way, now have to show their nurturing and caring sides. Another theme is family - like relationships. The hosts come together to take care of the baby, which is like a little family unit within the club.
Fanfiction about male Haruhi can also introduce new characters. These new characters could be rivals for Haruhi's attention or friends who help the male hosts understand her better. They can add new layers of complexity to the existing relationships in the Ouran Highschool Host Club universe.
Kyoya is a favorite for those who like more complex characters. His calculating nature and the secrets he might be hiding can be explored in fanfiction. For instance, a story that delves into his family's influence on his actions within the host club.
A 'what - if' scenario where Haruhi is actually from a wealthy family but has been hiding it all along. This would add a new layer of mystery and drama to the relationships within the host club.
The fanfiction about male Haruhi in Ouran Highschool Host Club can also focus on character backstories. Maybe a host has a secret past that is only revealed through his interactions with Haruhi. It could be something like a long - lost family connection or a hidden talent. These stories add depth to the characters and make the fanfiction a really engaging read.
