What is that one KPOP song that could breathe life into you on your deathbed?

For me, it's TVXQ's Doushite kimiwo sukini natteshimattandarou
It's the way the song starts and the melody just revives something in my heart. It's so nostalgic in a way I can't even put it in words. I don't even need to mention the vocals. IT'S TVXQ. I could be in a coma and wake up if I listen to it. This song would prolly even save me from Vecna lol.
