After hunting for this alleged oneshot release, I've determined the release information is incorrect; shoujoroom only released a chinese raw scan, never an english translation of this manga. Release log: http://shoujoroom.hostrocket.com/index.htm; project list: http://shoujoroom.hostrocket.com/project.php. Since I don't know how to edit releases, this notice will have to do for now so other people are spared trying to find this.
