Is he really going to sing to me? Ten points best answer!!!!!!!!!!!?

I was supposed to hang out with the guy I like tomorrow. I don't know him in person. We text a lot/talk on FB, but we're being set up by a mutual friend, and go to the same school (I've seen him before.) He can't go because he has to work, but he told me he's going to find out where I live; from my best friend, come to my house, and serenade me with a song he's writing for me. All to make up for a "broken promise." (not going tomorrow) So, he likes me? Is he really going to do it? He's shy.
