Is this unprofessional or hoeish?

There’s a guy co worker who began to be friendly with em and I recognized he may have actually liked me and I grew to like him as well. We had good conversations at work, we talk as if we have known one another forever. We just clicked and vibed. It took him weeks to ask for my number and he then took his time to ask me out for breakfast and I accepted. Is this unprofessional to do. Neither of us are managers or supervisors. I don’t have a boyfriend and he doesn’t have a girlfriend, but I know when you just start to have fun or date or whatever with a co worker, you can be judged or things can get messy.
