As I looked through the pictures that I've taken in previous time, I found that how EXHAUSTED I was during exam period.

This is when I studied for Math!!! You can see the calculator, and the math question book haha I remember that time was very hard and sleepy that I could hardly open my eyes.

And I think that's why I wore a sunglasses and took photo haha so sleepy and tired that I couldn't aware that that time was night? maybe haha
