Disclaimer - The smut here isn't 4P LOL, it's a normal 2-person romance and actually only 1 scene but better to put the smut tag for people who wants to avoid it.
Akari's grandmother told her to move out of their house and live at a new place. Turns out the place his moving in is a share house with 4 hot guys living in it. In exchange for free rent, Akari's grandmother wants these four to make her into a better woman. Will they be able to transform Akari into one?
