<human>: Alright so I'm leaving my job in about 2 weeks and plan on asking out my coworker for a lunch date/coffee. Problem is recently she's been really close with another guy at my work. I've overheard people mentioning both their names together frequently and they seem to be laughing a bit when I see them talking. I'm pretty sure they're not dating, but there looks like there's something there and I'm not sure if I should interfere. (I know the guy is into her 100%, just not sure if the feeling is mutual.)

The positives for me are that, although we don't get to talk often, She usually greets me with a smile every day and a simple "Hey" and I've caught her staring at me a few times as well. Even today she walked into work and had a big smile on her face when she saw me. I'm not the best at reading signals but imo there's something there and she may be interested. Also during out infrequent conversations she's opened up quite a bit for a (mostly) shy girl.

So I guess my question would be, should I bother asking her out? If so, Should I casually bring up something along the lines of "Are you and ____ going out? you seem pretty close" for confirmation before I ask her out? Or is there a better approach that I haven't thought about.

Can you give me a shortened version of the text?
<bot>: Coworker[M] seems really close to Coworker[F] that I'm interested in, unsure if I should still try and pursue her before I quit my job.
