你的手臂彷佛是我的城堡，你的心是我的天空。

Your arms are my castle, your heart is my sky.

愿我的心是一朵鲜花，盛开在你的天空下，为你增添一点温馨的情调，为你的快乐增添一片美丽的光华！

My heart is like a flower blooming in your sky, for you to add a little warm ambience for your pleasure to add a beautiful Guanghua!

偶然我是天空里的一片云，偶尔投影在你的波心——你不必讶异，更无须欢喜——在转瞬间消灭了踪影。

Chance I am a cloud in the sky, a chance shadow on the wave of your heart. Don't be surprised, Or too elated; in an instant I shall vanish without trace.
