Maiko felt suffocated by her husband's controlling nature...
They were never blessed with children, but the two of them had lived a reasonably happy life together.
However, a few years ago, her husband began to gradually restrict her, stressed by the competition for promotions at his company.
Because of this, Maiko was forced to quit her job and became a full-time housewife.
Furthermore, she was forbidden from going out, and her only relief was venturing out during the day while her husband was at work.
One day, while complaining about her home life to a junior colleague, she was introduced to a certain website.
She felt stressed by her husband's control but didn't want a divorce... yet... she felt like she was suffocating.
Yes... Maiko was seeking a "convenient escape."
Around that time, Maiko learned that "more and more women have a desire to be bound."
Encouraged by her junior, and despite the lingering guilt, Maiko took a step into an unknown world.
A new world was waiting for her there...
Maiko, who had suffered from emotional restriction, releases her unknown sexuality by being physically bound.
