Hahahhaa, I think even u read so many answers here by other forum members, it will still puzzle you and make u crazy sometimes thinking about it. Even with all the answers in here, you will still be like "Does he like me, wat if I'm wrong?" etc etc.

Bottom line, if you're interested as well, just hang out more with him lor even in a group. Eventually he might make a move to ask you out alone. All the best to ya.
