The 🧑 person emoji is a relatively neutral representation of a human being. In texting, it's often used as a generic placeholder when referring to someone in a non-specific way. From a friend, it could mean "this person" or "that person" without gendering them. From a romantic partner, it may indicate they're thinking of you in an abstract, non-sexual way. Used by a stranger, the 🧑 emoji is typically just a way to refer to a third party without assumptions. Overall, it's a fairly blank slate - the meaning depends heavily on the context and relationship.
