<human>: I started at this job two months ago. At the beginning, this particular coworker was very helpful and kind in helping me figure out stuff and getting the hang of things. He's been consistently nice, and is just a really good person overall. 

Next month, he'll be transferring to another branch of the company at another location, which kinda bums me out because I won't see him at work anymore. We don't have any mutual friends outside of work, and to be honest I do not know him all that well. But I do know that he is someone I would like to keep in my life. 

He comes across as very friendly, competent at his job, thoughtful, a bit shy at times, and slightly dorky (in the best way). The thing is, I don't know what I should do, if anything. I've talked about the situation with some of my close friends and they've encouraged me to be a little more proactive, since he'll be relocating shortly and if things don't go so well I won't see him again anyway. 

But I also worry that maybe I'm rushing things. I haven't known him for that long, and I still don't know him well. Plus I worry about how him knowing that I like him may impact our professional relationship.

Can you give me a shortened version of the text?
<bot>: I really like a coworker, who is relocating in a month. I don't know him that well (yet). What should I do?
