你不在我身旁，世界也显得暗淡无光。

The world looks bleak without you here by my side.

你是我心中的暖洋，即使你不在我身旁。

You are in my heart warm ocean, even if you're not by my side.

如果你不在我的身旁，纵然有繁星满天，照亮夜空如白昼，在我看来仍是暗无天日。

Might you realize that even if every star shone in the sky and turned night into day, that it would still be darkness without you by my side?
