in a world where a disease kills 95 percent of its victims, and the remaining five percent gain unwordly abilities, how does newly orphaned hyunjin deal with a past of underage gambling, conning, and joblessness?   in other words, spy and do good hyunjin, weak supernatural heejin, and a color obsessed yerim that enjoys painting far too much. 

2jin as violinists, and maybe Hyunjin doesn't care at all.

Where Hyunjin hides her secret in a zombie-infested world, in the most unconventional way possible. While also fighting zombies in the most unconventional ways possible.   Or where concerned Heejin questions how Hyunjin is still alive after fighting her way through the zombie apocalypse with a water gun filled with vinegar and a makeshift spear.
