Well, without more context about Sanji's story, it's difficult to determine exactly who the little girl is. It could be a childhood acquaintance of Sanji, or perhaps a character he meets during his adventures. Maybe she is someone related to a quest or a mystery in the story.
I think it might have been a character introduced to add depth to Sanji's backstory and motivations. But without more context, it's hard to say for sure.
Once upon a time, a little girl went on a hike with her family in the forest. She got separated from them but she was very brave. She remembered the things her father had taught her about survival. She found a small stream and followed it until she found her family waiting for her at a campsite downstream.
We can learn about the importance of understanding emotions. If this girl is angry, it shows that there are underlying issues that need to be addressed.
They could simply unzip it if it has a zipper. If it's a button - up dress, carefully unbutton it. Maybe ask for help from someone nearby if they can't reach all the buttons or the zipper.
One important element is his family background in the Vinsmoke family. They were a family focused on power and had no place for Sanji's kindness. His passion for cooking was also crucial. It was what made him different from his family. And finally, his escape and the journey he had to endure to become a part of the Straw Hat pirates are significant elements. He had to face many challenges and learn a lot on his own, which shaped his personality.
Sanji was born into the Vinsmoke family. His family was cruel and saw him as a disappointment. They treated him poorly because he showed kindness and emotions which they considered weak. Sanji ran away and ended up on a ship where he learned to cook and started his journey towards becoming a great chef and a Straw Hat pirate.
The key elements in Sanji's back story are his family, the Vinsmokes. His different nature compared to his siblings is also important. And of course, his love for cooking.
