Very different interesting idea approach - pov of being infatuated with a co-worker. A bit off the beaten path.

As far as nuts and bolts. IMO, the mix is great. The lyrics are well crafted and it's got a good tune. The harmonies are very nice too.

Solid writing and production.

(BTW, I listened to your other song that Danny mentioned. You should post it here in the Users Showcase too when you get a chance.)
