What does a guy mean when he compliments me then says just kidding?

Okay so this guy came up to me and said you are kinda cute. And i said thanks. He started to walk away and said just kidding. And i said ik. The next day he was walking by with one of his friends while i was sitting at my table then we made eye contact and he said hey it you again. Then i said hey. Then when he was walking away he said just kidding. He is only a year older than me. Is he just teasing me or does he like me?
