If a guy implies you are drawing him in your portraits is he trying to humiliate you or just tease you?

For fun I like to sketch artistic pics some of which are couple pics. Recently this guy I haven’t spoken to in a long time reached out through a cryptic account to ask why I was drawing him and that my previous portrait depicted him and I. I didn’t know what to say and thought it was a joke by one of my friends but apparently it wasn’t. Is this guy just trying to draw attention to himself?
