唔該幫我睇睇d grammar 啱唔啱,thanks!!

The main (characters) character in this story is (the) Fox. He is a naughty boy, he (oftens) often gets himself in trouble. One day, he was in the library, he was reading a very interesting book, he laughed and laughed, he couldn't stop laughing. At last, he was driven out by his teacher, so as his friends.
Fox - no need to add "the" as it is a name

The main character of this story is the Fox. He is naughty and often gets himself into trouble. One day, while he was in the library reading a very interesting book. He could not stop laughning, he and his friends were driven out by his teacher.

BIG problem - you use too many 'HE' Can you use another word - connection word (e.g. and, thus) to replace it?

characters - character 因為你得一個Fox

有個問題，he was driven out by his teacher, so as his friends ，我唔係好明你so as his friends,佢老師又點會so as his friends.呢？
