Maybe the OC is a childhood friend of Kyoya's who moved away years ago. She returns to Japan and enrolls in Ouran. Kyoya initially doesn't recognize her, but as they interact in the Host Club, memories start to come back. There could be a lot of flashbacks to their childhood, and they have to re - establish their relationship while also dealing with the other members of the Host Club and the social hierarchy at the school. This would allow for a lot of character development and exploration of their past and present feelings.
The OC could be a transfer student from a rival school who is sent to spy on the Host Club for some reason. But as she gets to know Kyoya, she realizes he's not what she expected. For example, she might see his shrewd business side at first but then discover his more vulnerable and kind aspects. They have to navigate their growing relationship while also dealing with the drama between the two schools.
One plot idea could be that the OC is a new student at Ouran. She accidentally stumbles into the Host Club and catches Kyoya's attention because she's not immediately smitten like other girls. He then tries to figure out her motives and in the process, they start to develop feelings for each other.
Perhaps 'The Unlikely Bond: Kyoya x OC in Ouran Highschool Host Club'. This title emphasizes the idea that their relationship might be unexpected or different from what one might initially think in the setting of the host club.
One popular plot idea could be the male OC being a new transfer student at Ouran Highschool who accidentally stumbles upon the Host Club. He has a unique talent, like being an amazing pianist, which catches the attention of the club members and clients alike. Another idea is that the male OC has a mysterious past that slowly unfolds as he becomes part of the Host Club, adding an element of intrigue to the story. Maybe he's related to one of the existing characters in a way no one expected.
The male OC could be an undercover journalist. He joins the host club to expose the so - called 'extravagant lifestyle' of the rich students. As he spends more time in the club, he starts to understand the real personalities behind the hosts and realizes that there's more to them than just their wealthy facades. This could lead to a story full of self - discovery and unexpected friendships.
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.
Well, you could have an OC who is an exchange student from a foreign country. He could bring different cultural elements into the host club, which causes some interesting interactions, especially in a yaoi - centered story. For example, his different view on relationships and his unique charm might attract one of the existing members in a more than friendly way. You could also explore how the other host club members react to this new relationship dynamic.
One common theme is the discovery of feelings. Since Kyoya is usually so calculating and Haruhi is so down - to - earth, it's interesting to see how they come to realize their feelings for each other.
A crossover with a detective anime would also be cool. The host club gets involved in solving a mystery. Maybe Haruhi could use her practical thinking skills to help the detective figure out the clues, while the other host club members provide distractions or use their unique personalities to get information from suspects.
The theme of self - discovery also frequently appears. As the OC gets involved with Mori, they often discover new aspects of themselves. This could be in terms of their own courage, as they face the challenges of being part of the Host Club world, or their own capacity for love as they interact with Mori on a deeper level.
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.
Sure. One great fanfic could be 'The Unspoken Bond' which delves deep into the relationship between Kyoya and Haruhi. It has a really interesting plot where they face challenges together in the Host Club and their feelings start to develop in a very natural way.
