Okay lah, some advice for this "lady with a crush".
Next time, you see him before tutorial, walk up to him, say a quick
hello and then ask him anything about the lesson.
Later if you are thick-skinned enough, jio him for a lunch or
something, maybe for the reason of wanting to ask him more
questions of what you have been learning etc blah blah
blah.....
Then, if he accepts the lunch, maybe you can start off by
initiating any sort of conversation under the sun, crapping lah.
Most important thing is be natural, you don't want to show your
"true feelings" for him too soon lest he get scared of you.....
Try it out.
