若你是深海我愿沉溺
[ruò nĭ shì shēn hăi wŏ yuàn chén nì]
This translates to 'If you are the deep sea, I am willing to drown'. It implies a profound and overwhelming love for someone, expressing that one would be ready to give up everything for the person they love, just like drowning in the deep sea without any hesitation.
