admiration. is it normal?

to preface: i’m really looking for advice, and i’m not sure if this is the right topic to put this in, but i couldn’t really find one that matched. i (18 f) have been working at my job for a little over 4 months. I have this coworker (47 m) who recently i’ve noticed i’ve been gravitating towards. he says good morning to me every morning, we’ve had deep conversations about life, but also just goof off and joke around when we get the chance. He’s a very monotone person, very guarded, and blocks most of the other employees out except for me and the 2 other people he’s constantly in contact with. (there’s 7 employees total). I’m really just wondering if this is normal? I just adore him, he’s not an attractive person physically but there’s something ab him I just love. NOT TO MENTION he was the winner of a popular competition show many years ago, so I’m not sure if i just admire him and am almost “startstruck” and that’s what it is. I should also add, he is the youngest of ALL of my coworkers. we started out super rocky, i was convinced he didn’t like me, he once yelled at me and i convinced myself i was never going to talk to him again. i feel like this is so weird but like idk. i don’t want to date him, he’s just someone i want to be with as much as possible. is it admiration? is it normal? or am i just weird? any advice would be greatly appreciated.
