The furthest distance in the world 姓名 Is not between life and death 学号 But when I stand in front of you Yet you don't know that I love you. The furthest distance in the world Is not when I stand in front of you Yet you can't see my love
But when undoubtedly knowing the love from both Yet cannot be together.

The furthest distance in the world Is not being apart while being in love But when I plainly cannot resist the yearning Yet pretending you have never been in my heart. The furthest distance in the world Is not struggling against the tides But using one's indifferent heart To dig an uncrossable river For the one who loves you.
