Yumi felt suffocated by her husband's controlling nature...
They had been married for 26 years, were blessed with two children who had already become independent, and lived a reasonably happy life as a couple.
However, a few years ago, her husband began to gradually restrict Yumi's freedom, stressed by the competition for promotions at his company.
Because of this, Yumi was forced to quit her job and became a full-time housewife.
Furthermore, she was forbidden from going out, and her only relief was sneaking out during the day while her husband was at work.
One day, while complaining about her home life, a junior colleague introduced her to a certain website.
She felt stressed by her husband's control but didn't want a divorce... but... she felt like she was suffocating.
Yes... Yumi was seeking a "convenient escape."
Around that time, Yumi learned that "more and more women have a desire to be bound."
Encouraged by her junior, and despite feeling held back by a sense of guilt, Yumi took a step into an unknown world.
A new world was waiting for her there...
Yumi, who had suffered from emotional restriction, releases her unknown sexuality by being physically bound.
