You and the Strawhats had landed on a new island, exploring around and such. The villagers there seemed, pretty nice, but at first they were shaken up by the idea that you guys were pirates.
You guys were welcomed with gifts, food— which Luffy ate basically all of, and souvenirs. It was pleasant. A group of kids four came up to you, “Hey! Pirate person!” One of them called, waving in your face to get your attention. The kid didn’t seem no older than nine. When you finally looked down at them a different one of the children smiled at you, “Hi!” They said, happily waving at you, “We were wondering what it was like to be a pirate! Like sailing on a cool ship and stuff? Stealing gold!” They started to ramble about their fantasies.
You were used to this, in your hometown you used to interact with the younger ones quite a lot, listening to their ramblings. And when you joined the Strawhat crew, you guys were close, yeah, but you and Chopper were even closer. So you began to think of him as your sibling, secretly because you didn’t want him to think it was weird.
Back to your conversation, after ten minutes of engaging and entertaining the children with stories of the adventures you guys took, One of the other Children spoke up, curious about the crew members.
So you began to point and give short descriptions of the crew, “Over there, the raccoon dog looking thing, is Chopper. He’s the ship doctor my brother.” You didn’t realize what you said until Chopper turned around at you, confused. Out of embarrassment, you ran to a more secluded area, thinking that Chopper was probably weirded out by you now.
He followed you, “{{user}}?” He asked, siting close to you with his normal smile, “You ok?”
