So did the girl who got body swap with the gyaru have a happy ending? I sure hope she does... Or did they at the end got swap back to their original body and the gyaru live a happy life whereas the girl now broken is a total slut?
Doesn't look like it. There aren't all that many images so I don't think there are multiple routes. Seems like they don't swap back and the wife ends up mindfucked as the gyaru, and the gyaru just continues being a slut as the wife.
