Ouran High School Host Club is a good one. Although the Манга goes deeper into it than the anime. Also, Fruits Basket. However, the Манга is much еще romantic than the Аниме and like Ouran it goes deeper into the plot than the anime, so I suggest Чтение the manga. Vampire Knight is a good one, too. It's a bit darker, though. It's another one that the Манга goes deeper into, but the Аниме covered most of it from what I can see. But they dragged the first book out for like 4 episodes... it's like that with most Аниме but the way Vampire Knight was written, it was made to be very fast-paced.
