Why would a friend of my crush send the video of my crush to me?

Yesterday I was chatting with a guy who also happen to my crush's friend and when I asked where he was and he suddenly sent the video of my crush where he actually asked my crush to answer my question. And this guy don't know about my feelings toward my crush. Then why would he send this video? Was it just coincidence?
