I should have understood that we are separated by death in two worlds. Right from the beginning. No matter how hard I try, I can only be a piece of sand on his seashore. He had to pounce through me onto the rolling waves, he had no choice. Now he holds my piece of sand in his hand, just hoping that he will not be so lonely on the road. But in his eyes, I am just that piece of sand after all. I couldn't stop him, let alone save him from the waves. Even if I regard him as my whole world, I am just a piece of sand in his hand.
