Each girl has her own back story with Kirito where he flirts and cares for them, but they make it pretty obvious that he only has serious romantic feelings for Asuna (probably because she was his first, they survived life and death together, and they were together for 2 whole years which is pretty damn long if you compare it to how much time he was with the other girls).
