#004 of 2D Dream Bunko/Pocketnovels. This is still considered as "early work" from this label, means it is more harsh on the contents than what it is now. There are certain turnovers in this book, from femdom to masochist before turning back again, so don't get misled by the only colored illustration :).
there's no info on mugi atm, and no digital ver. was made.
