Liking someone is more superficial. If you like someone, you'd hang out or chill together. Caring is when you're around for the bad stuff. You also care about what happens in their life, even the part you're not involved in.
Caring about someone means being willing to get up at 3AM if you get a phone call saying they got thrown out of a party and they need a ride home, and going out, getting them home, and making sure they're all right.2
