I noticed that volume 19.5 was given away during one of the weeks when they aired the irregular movie, unlike the others though, this one seems to be an alternate storyline. Has anyone read this and does anyone know if they plan to continue this and make a volume 20.5 etc. and have two different endings for the series, I'm confused as to what events were changed to make this an "alternate" story. With Mayumi on the cover, can we assume that this version of the series will finish with a different romantic ending that the regular series?
