Most Helpful Guy
It doesn't always matter if you give obvious hints to a shy person. Especially if they've never actually dated/had a girlfriend before.
There's nothing stopping you from taking the first steps yourself. It's 2015 and everyone wants gender equality, so stop sitting on your hands and waiting for him. Go do it yourself. It won't make you look desperate. It's merely you going after something you want.

Wait a minute. So he's shy because he's asian? Really? Shyness does not stem from your race. It has nothing to do with your race.
Just because a guy may be certain you like them, there is still that fear of rejection looming over their heads. I've liked guys before a lot, but turned them down when they asked me out. "Obvious hints" mean nothing. They are just hints. Guys are oblivious to them. If he doesn't ask you out, it's because he's shy, nervous and probably intimidated by you.
