Are the female colleagues in this company hinting at me?

Haha, of course, it can even be said that this is not a hint, but an express!

As for the need to chase her, I don't think so. As you said, in fact, you are quite close to her, and you can get it with a light grasp!

You should observe and know more about other aspects in contact, especially her personality. As long as it belongs to the kind you like, then you can make a decision!
