I can't stop thinking about my supervisor. what can I do?

We work as contact security officers. Him being my captain/ boss/ supervisor. But since we are security officers we don't see each other very often because we work at different locations. But I remember the day I first met him he came to pick up some paper work from where I was working. The sight of him blanked my mind of all other thoughts. The way he smiled at me, he looked like an angel. It didn't help that he said that he was impressed by my proper dialect and he said I was cute. I don't know if him calling me cute was just a friendly gesture or he found me attractive. I just saw him yesterday for the second time in months, he was picking up more paper work. This time he stuck around to hold small talk with me. Again smiling so wonderfully at me, asking if I ate and how I liked being a security and asking me about my phone amongst other random topics. But the thing is, is that to all of the other officers he's really mean to them.... He's a I can admit but whenever I come in contact with him he's nothing but extremely sweet and nice. I really want to be with a man like him, he's everything I look for in a man but I don't even know his first name.I don't know where to start. I can't get him out of my head. He's so.... Perfect. How can I give him hints? I'm 75% sure that he at least find me attractive andf unique....I am pretty lol. But he's my boss to so it's risky...I like my job. I'm at a lost.
