A co-worker says he and I "just click". Do you think he's interested in me?

So there is this guy at my work. I've known him for the past year but it wasn't until this past month that I really started to work with him (we used to work in different areas) we found out we have a lot in common and have been getting close. I have always found him to be pretty cute. I always laugh at his jokes but I haven't done much else to show I'm interested in him. But today he was talking about our connection with another one of our co-workers (I was also in the conversation) and he said we just click. Should I take this as a hint he's romantically interested or should I brush it off?
