Mako felt suffocated by her husband's control… Though they had no children, the couple lived a relatively happy life. However, several years ago, her husband started to control Mako more as he accumulated stress from competition for promotion at work. Because of this, Mako was forced to quit her job and became a housewife. I was even forbidden from going out, and the only chance to relax was when my husband went to work during the day. One day, while I was complaining about family troubles to a junior colleague, they introduced me to a website. Although I felt stressed by my husband's control, I didn't want a divorce... but... if things go on like this, I'll suffocate. Yeah... Mako had been seeking 'convenient fun.' Just then, she learned that 'the number of women who want to be tied up is increasing recently.' Pushed by a junior colleague, despite feeling guilty, Mako took her first step into the unknown. There, a new world awaited her… Mako, who was suffering from restraints, opens up to unknown sexuality by being bound.
