<human>: Recently after a bunch of my co-workers hung out at my apartment for a day, I discovered I have feelings for one of them [21F]. We've talked here and there for about a semester at work and we have a lot in common. Besides the aforementioned hang out, we've never hung out outside of work. 

Grand romantic gesture:

Valentine's day is coming up, as if you didn't know, and I've written a short song asking her to come over and watch a movie for V-Day. My plan was to record a video of me playing the song and send it to her on FB (probably in a message to avoid any embarrassment). I don't profess my love for her in or anything. I just made some cute references to past conversations. It's pretty light-hearted and tongue-in-cheek.

Now here's my question: Is this creepy? Or cute? I polled my friends and got a mixed bag of answers. Do I not know her well enough? We have established a good rapport but never hung out without other people around. I get the sense that she likes me too as we are sort of flirtatious around each other. But how badly could this backfire? Does it just wholly depend on whether or not she likes me in the first place?

Give me the gist of the text in a nutshell
