【ONE】 Life Prolonging Treatment (延命治療)

It's an ONE cover/song from Neru :')I've always loved Life Prolonging Treatment (or Neru's songs in general, really), so listening to the ONE version is just... amazing. And as usual, I still like IA's voice better for the lower pitch section, but damn, ONE's version of the chorus is absolutely delightful.
