Having crush on a guy I could barely talk to

Hey, it is not really a confession but I just wanted to share this. I am working part-time at a restaurant. There is a group of people who do the part-time job like us. I began to fall for a guy who is very attractive. Even though I barely talk to him but I kinda sense his dorky side he didn’t show and it is really cute. But the contract is almost over and we probably wouldn’t see each other again. Should I leave things the way it is or should I try to talk to him? If I should talk to him then WHAT should I talk to him? I didn’t hope that he would be interested in me but I just hope that we could have some chitchat ☺️
