Who would ever want to be stuck in that town.

Both.

She escapes her monotonous life by inserting herself in her stories.

"There must be more than this provincial LIIIIIIIIFE!"

Both! An adventurous person would of course get bored with the same old provincial life they live. She is bored but she also wants a life of adventure.

"I want adventure in the great wide somewhere! I want it more than I can tell!"

Adventurous people don't sit around wishing for adventures; they go out and find them. Belle suffers from small town boredom but doesn't actually fix the issue by changing her life into something more stimulating as she craves. This is pretty common for her personality type (a Si/Ne user).

Heck, even when she gets to live in a magical castle, she does the same stuff she did at home- read, go on walks, feed the birds. I think it's ok to not be adventurous, btw.

Also, *I'd* like to stay there. It's a pretty, quaint place. I'd have my own adventures in the great, wide somewhere we see right outside the village in those gorgeous French hills.
