Part of the lyrics are: your good to me still echoes in the memory ear, those drops how can I forget, the next life is still waiting for you, waiting for you to rely on, no longer let tears torture themselves, and you together to write the legend of 爰, the next life is still waiting for you, and you together, may the love of us no longer separate.
