Many years have passed since Ouran Highschool Host Club ended so I don’t feel bad about spoiling anything if you wish to go further. At this point if you were planning on reading the manga you would have done so already. We’ll briefly cover 5 or 6 major points to the rest of the manga.
We’ll keep this brief and only mention the most important parts.
1st. Haruhi falls in love with Tamaki first and she doesn’t know quite how to deal with it. She becomes incredibly nervious around Tamaki which he doesn’t really know how to interpret her feelings.
2nd. The Host Club meets with Tamaki’s mom.
3rd. Tamaki and Haruhi kiss, by accident. And only the side of their lips touched.
4th. Yuzuru Suoh, Tamaki’s father, takes the company over from underneath Tamaki’s grandmother by force. Which actually displeases Tamaki because what he wants is a family and not wealth or fame. Tamaki tries his best to console his grandmother who has only had distaste for him so far and asks that he leave her alone. Tamaki’s dad is confused by this since he thought that Tamaki would be happy that he can now see his mother, but he refuses to do so without his grandmother’s permission. Tamaki genuinely wins over his grandmother and his family finally learns how forgive one another.
5. Tamaki begins to learn how to take over the family business. Him and Haruhi start dating. Haruhi becomes close friends with the Suoh family lawyer who was a kohai (fellow student in a lower year) of her mother. Haruhi decides to study abroad in France. Honey and Mori struggle with their senior year ending and having to leave the Host Club. In the last chapter Tamaki follows Haruhi to France where he says he can study how to take over the family business in the Suoh France branch. In the end everyone at the school knows about Haruhi and Tamaki, though they all think that Tamaki and Haruhi are gay. Until after Haruhi and Tamaki board the plane does word comes out that Haruhi is actually a girl. Tamaki arranges it so that Haruhi will be living next to him. The gang follow them to France also, Honey and Mori say they’ll begin college in France. Haruhi is a bit angy by this since she thought this would be her chance to be on her own, but is overall happy. The End.
