My coworker is protective of me, does that mean anything?

He saw that I got upset bc of some random jerk and he immediately asked me what happened and if I need any help. It wasn't a big deal but he still told me that if someone is rude to me I can call him/ask for his help anytime. Is there a chance that he might like me?
