I owe you a tear in my previous life.

It should be this song.

I owe you a tear in my last life. Li Qianshan listened to the lyrics.

The taste of pain in the bone marrow. One side is heaven, and the other side is hell. I ... I want to wait for the next reincarnation, with volcanoes on one side and seawater on the other. Who am I without you? Even if I turn to dust. Won't make you regret being with you in this life. I owe you a tear in my last life.
