是不是我就是你想要的明天是不是沧海桑田你都在身边
[shì bù shì wŏ jiù shì nĭ xiăng yào de míng tiān shì bù shì cāng hăi sāng tián nĭ dōu zài shēn biān]
Does tomorrow bring what we both desire, and will you be beside me through all changes? Questioning about future hopes and the steadfastness of someone staying no matter how much circumstances alter.
