I'm not sure if there are a large number of such fanfics, but it's quite common for fans to create works based on their favorite characters from clubs in anime or manga. So it's possible to find some by using relevant search terms on popular fanfic websites. For example, on AO3, you can use the character names and the name of the club in the search bar to see if any results pop up.
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.
There's also 'Mori's New Beginning' which is quite interesting. In this fanfiction, the OC is a transfer student who catches Mori's eye in a unique way. The story focuses on how their relationship evolves from initial acquaintance to something deeper, with lots of sweet and touching moments.
Sure. The Ouran Host Club manga has finished. It had a proper conclusion that covered all the important aspects and left a lasting impression on readers.
Naruto would probably be a very popular host. His sunny personality and ability to make people laugh would draw in a lot of customers. He's always full of energy and has a big heart, which would make guests feel welcome and happy in the host club.
Gray would be a popular host. His cool and aloof demeanor would attract a lot of customers. Girls might be drawn to his mysterious side and his good looks. Plus, his habit of accidentally stripping could add some comical moments to his hosting sessions.
The ending of the Host Club manga is quite unexpected and bittersweet. The characters' relationships evolve in complex ways, and there are some emotional resolutions.
