You don't know him so well yet. Use that to your advantage and make assumptions about him. You say you like different things, but that's only your assumption. Maybe you just haven't found the things you like both yet. Making assumptions about new people has worked very well for me in the past. I met this guy and I just assumed that he was into me. Three days later, he started to give me signs that he really was. You create the other person literally with what you think about them and who you expect them to be. So be careful with your thoughts and use the small timeframe in which you don't have a full image of the other person. It's much easier to start from scratch than to change something.
