Envy.

Background
Furukawa-P's 8th work and first with Luka. The song has a mellow yet melancholic tone, singing wistfully of things that will not be. The song was taken down by the producer after he retired from being a VOCALOID producer. This song has been featured on Peams.E.P as well as on the album named after it, (the army for your) ENVY E.P. Both album tracks use Hatsune Miku dark instead of Luka.
