Manhwa (probably)

I need some help remembering the title to a zombie manwha, if anyone knows it.

The undead were entirely conscious, and basically like normal people that (I think) were hunted by the government or some organisation despite still having their humanity.
The main guy had white hair, played the guitar and had a crush on an idol(?). There was a secondary character whose face was left as just a skull, and he was a chronic smoker.
I remember a strangely heartfelt scene that referenced ‘Photograph’ by Nickelback of all things, and the work may have opened up with ‘Creep’ by Radiohead? I think there was an Oasis song in there too.
… You’d think I’d be able to find it if I remembered it well enough, but alas, I am hoping someone can aid me here.
