Relax~ Let's try! ^_^
It is worth for you to express your feeling to her...
If you don't try, you won't know the truth...
If you try, you won't regret more...
Actually the girl doesn't know what do you feel about her...
Although you need to go to USA later, you should try it...
Because you still have choice, you will regret oneday if you give up...
I believe there may be a surprising result for you...
Apart from that, you should focus on your study too...
In fact it is important for you to study first...
It seems that you neglect your study while you LOVE a girl...
Wish you can succeed!! ^_^
