There are two actually. A "one-shot" of Mr.E under the same name, "A Zombie Girll Fell For Me".. it was done around 2015/16 I dunno. And a few years after came Cherry Road, C.R is the stable series of the comics, and this comic saga is a prequel (stated by the first comic, possibly a removed part by now)
TL;DR
This comic is a prequel, "A Zombie Fell For Me" is a one-shot from 2015'ish and Cherry Road is the one-shot continuation and remaster at the same time
