I may forget you if you leave me so long. But I won't if loving you have became a habit.

起初我也曾怀疑我是否会忘记你，但现在，爱你已成习惯，伴我生，随我死。

To leave you is to die for me.

若要离开你，于我与死无异。

As you have stolen my heart, why not keep going on?
既已窃吾心，何不窃吾身？

Through that I have sold my soul to you, then what you will done to me isn't important at all.

我既已将灵魂售之与君，如何处置便都悉听君便即可。
