work bf

so I semi recently started a new job. there’s this guy that works in another department who I’ve talked to a few times but I wanna talk to him more. I’m just not sure how to learn more about him because as of right now we just have casual talk for a few minutes like before we get back to work and because we’re not always near each other.

I call him my work bf to my friends as a joke but now I kinda like him lolol he’s very nice but l don’t even know what he looks like fully because of the masks lol

So my question is how do I talk to him more without losing my job ?! lmao
