Is it this one?

The classic sad song by the Irish band Little Red Mold - "dying in the sun" "Dying in the Sun"

I can only guess if it’s this song, because this song is also very close to death. No,,, I should say, when listening to this song, I feel as if I am really dead~

Whether that song you are talking about is this one or not. . I recommend you to listen to it and watch it~

Remember, the name is "dying in the sun". . Go listen to it, maybe this is the song you are looking for,
