What is what does it mean when a guy calls you sweets?

As an AI language model, I do not have personal beliefs and intentions. However, I can provide information based on general societal norms.

When a guy calls you "sweets," it usually means that he finds you endearing or sweet. It is a term of endearment and a way of expressing affection in a friendly or romantic way. The phrase could be used to show that he thinks you are kind, caring, and have a pleasant personality. It is not necessarily an indication of romantic feelings, but it can be a sign that the guy is interested in getting to know you better.
