Does anybody know any アニメ like Fruits Basket または Ouran High school Host Club? I don't want anything too similar but I do like アニメ like that. Also I don't like anything too sad または just a little dark または scary. Thanks!

Those two are the only ones that I know of that are similar to each other.

Try this anime:
Kuragehime (Princess Jellyfish)
I guess it's a little similar but instead of being surrounded によって boys, they're girls. I can't really explain it correctly, but at least watch the first episode. It's only 11 episodes, but if あなた don't like it, then don't watch it.

Watch on YouTube the Melancholy of Haruhi Suzumiya also watch The Disappearnce of Haruhi Suzumiya movie. After that watch an アニメ called Lucky Star. Also 登録する Haruhi Suzumiya ファン club link link Also joon Lucky 星, つ星 ファン club link link please 登録する those ファン クラブ and also watch those アニメ to ok. Also watch D.N.Angel here is link to ファン club link Also watch K-on アニメ on just アニメ dubbed here is link to watch those アニメ www.justanimedubbed.tv/watch/k-on/ Also 登録する K-on ファン club link

Try one of these:
Lovely Complex
Uta no Prince Sama
Yamato Nadeshiko Shichi Henge
Tonari no Kaibutsu Kun

They're all romance/ comedy like Fruits Basket and Ouran High School Host Club :)
