Well, in such fanfics, the writers often take the close relationship of the twins and expand on it in a romantic way. They might describe secret glances or special moments between them that are exclusive to their relationship. It could also involve how the other host club members react to this new aspect of their relationship, whether they are accepting or confused.
Often, the fanfics will play up their differences and how those differences complement each other in a romantic sense. For example, if one twin is more outgoing and the other more reserved, the fanfic might show how they balance each other out. Also, the host club setting is used to create interesting scenarios. Maybe they have to hide their relationship from the clients at first, which adds a layer of secrecy and intrigue.
Well, Harry could be really confused at first. Ouran is a very different world from Hogwarts. He might be shocked by the opulence of Ouran Academy and the strange club system there. Maybe he'd try to find a way to fit in while still being true to his wizard self.
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.
The Host Club members would probably be very curious. Tamaki might be the first to approach Harry, thinking he's some kind of exotic new guest. Haruhi would be more down - to - earth and might try to figure out what makes Harry so different.
I'm not sure specifically as there could be many different interpretations. It might be a fanfiction where the character Kaoru from Ouran does something that causes harm, either physically or emotionally, to another character in the Ouran universe.
A fanfic with this scenario could start with Harry arriving at Ouran Highschool on a rainy day. He has his trusty umbrella, which could be a family heirloom or a magical item. As he walks through the school grounds, the students of Ouran Highschool are intrigued by his different appearance and the old - fashioned umbrella.
