Japanaese title: 性転換後、親友と～相棒編～
An alternate take of the original story After My Gender Bending My Buddy and I.... The two storylines share the first four chapters and diverge afterwards. Chapter numbering restarts from 1 again at the beginning of the alternate storyline. Story continues at pixiv #47628617 / post #1815019.
The preferred reading order is the original story first, then this alternate take.
