Is it normal to talk again to someone you have only met once?

Exactly a year ago, I first met a guy who used to be a friend of one of my best friends. My friend met him in a party because he felt interested about her, but she turn him down. Anyway, they got along well, so they stayed in contact. One day, a year ago, some friends and I met him and we spent together the evening. I found him very nice, smart and above all really handsome, so I was hoping to meet him again. We even exchanged numbers, but we didn't talk to each other again. After that day, my friend and the guy stopped talking to each other, not because they were angry or something happened, but simply because they lost contact. Yesterday I was on Instagram and on suggestions I saw him, I remembered that she looked like a guy who was worth of it and I felt sad because we didn't have time to get to know each other. I started following him on Instagram and he did it as well. I'd like to contact him again, but I don't want to be creepy, besides, probably he doesn't remember me. Do you think that I should try anyway?
