They like you means they can be very good friends of you. If now the question is about love, if you become very friendly with them they will start understanding what you actually are and what you actually like about. Who do you want to love or what type of mindset you have, they need to spend time with you to know more about you. These will help them to proceed further relation with you. In my experience there are couple of people whom I didn't like at all when i met them for the first time. However after a certain period of time I found them very good people as human.
I will prefer not to deny any friendship at the very beginning. I would rather try to find why I dislike them while they like me. Isn't it strange that I like someone but he/she dislike me!!
Life is always stressful so take it easy.
