Is it common for a shy/introverted guy to act this way?

I think he’s too shy to interact with my stories.

Is it bad sign if guy views every single instagram story of mine but he doesn’t interact with them ( he doesn’t reply to my stories or answer polls?

by the way me and him barely know each other. I’ve replied to his stories couple times in the past and he seemed to like talking to me. I stopped doing that. Is it possible that he could still be interested in me despite being passive? He doesn’t even answer my emoji slide but views every single story and always looks at me/recognizes me in public.
