How to reply to others' confession?

There will eventually be weak water as the sea, and then send acacia as Wushan. There will always be weak water to replace the sea: weak water lost to the sea, that is to say, there will always be someone I don't love so much to replace you I love deeply. Send acacia to Wushan again: the original is forever amber, which means I don't care about anyone except you, and then I can silently tell you my thoughts.

The origin of this sentence is because a famous poet named Yuan Zhen wrote a poem in the Tang Dynasty, one of which is that Hai is very sad, which can be roughly understood as that you have a very satisfied object. After breaking up, you find someone else and feel together with him.

This is comparing him to the sea, comparing others to water, and then someone will reply to Yuan Zhen's poem with what you said, which means that someone will eventually replace the once irreplaceable sea in your heart.
