If a guy bullies you when you’re younger does that mean he’s interested in you?

So I remember when I was young and had this guy bully me relentlessly throughout my early high school years. He eventually moved before anything actually came out of it but I was told constantly it’s only because he’s into you. Like is that really a thing? And if so why? Why go out of your way to bully the person you like? Seems a bit counterproductive in my opinion.
