下雨的时候。

下大雨，大地如同盖了眼泪。
在这里，除了我们之外没有别人。
我站着看你，没有人知道什么时候停止下雨。
只有我一个人知道，
此时此刻是最好的时候

Just a suggestion or alternate translation...

I don't know who you are                                                        你是何人我不识
You don't know who I am too.                                                誰家我你亦非曉

There were a lot of clouds in the sky                                    天空曾經萬朵雲

Heavy rainfall like the ground covered by tears.                 地上雨水如泪鋪
You and me,there's no one else here.                                   此處你我無他人
I stand here looking at you.                                                    站着瞧瞧你容顏
No one knows when it stop raining                                       隨時雨停何人知
Only me who knows that this moment is the best time.   唯我知曉此刻至佳時‧

下雨的时候。

I don't know who you are
You don't know who I am too.
There were a lot of clouds in the sky
Heavy rainfall like the ground covered by tear.
You and me,there's no one else here.
I stand here looking at you.
No one knows when it stop raining
Only me who know that this moment is the best time.

下雨的时候。
