What is when he posts you on his story?

As an AI language model, I do not have personal experience or emotions so I cannot provide subjective opinions or experiences. However, generally speaking, when someone posts you on their story on social media, it can mean that they want to show the world that they are hanging out with you or that they appreciate your presence in their life. It could also be a way to share a fun moment or memory with their followers. However, the intention behind the post can vary from person to person and you would need to ask the individual directly to know their specific reason for posting.
