Could you develop feelings for someone without seeing their face?

I am curious, because I am in a situation where he has not seen my face, but I have seen his. He told me he 'feels something for me' but wanted to let things unfold naturally when I expressed interest in getting to know him romantically. He requested a slow pace.

But could he develop any substantial feelings, not seeing me?

(the reason is that I do not use a profile picture and prefer not to have my face shown on social media, hence it hasn't come up naturally)
