Dose this Korean boy like me?

from what i know, when a guy ask a girl to call him oppa means he want to be closer to the girl and hopefully they can be bf/gf.. usually if u are not close to someone, u dont really call them oppa or unnie because they might be uncomfortable with that.. the fact that he asked u to call him oppa first, it shows that he is interested in you or like you. but in korea, there are those who call oppa but are not in a relationship, just that they are close
