Is it possible to be attracted to someone virtually in a professional setting?

Mind you I work with this guy. I’ve never seen him in my life, and don’t know anything about him like his age or what state he lives in. Every time he joins Zoom I get excited when I see his name and hear his voice. I also just admire his work ethic. He’s very smart, works very hard, and helps everyone out. Is this normal or am I just experiencing admiration for him?
