Chisato felt suffocated by her husband's control…
Married to her husband for 17 years, they hadn't been blessed with children but had lived a reasonably happy life as a couple.
However, around five years ago, her husband started to become controlling due to stress from competition at work.
Because of this, Chisato was forced to quit her job and became a full-time housewife. She was even forbidden from going out, with the only time she could relax being when her husband went to work during the day.
One day, while venting about her family troubles to a junior colleague, Chisato found herself revealing her true feelings.
She felt stressed by her husband's control but didn't want a divorce… yet, if things continued like this, she would suffocate.
That's right… Chisato was seeking 'convenient fun'.
It was around that time that Chisato learned about the increasing number of women who desired to be restrained.
Pushed by her junior colleague, despite feeling a sense of taboo and hesitation, Chisato took her first step into an unknown world.
There, a new world awaited Chisato…
Chisato, who had been suffering from restraint, found liberation in her unknown desires through being restrained.
