Plot

The series follows Shiori Miyagi, a lonely high school student living on an allowance. She uses this allowance to pay Hazuki Sendai, her popular classmate, to meet her once a week. During these three-hour long meetups, Shiori asks Hazuki to follow her commands. One day, Shiori asks Hazuki to remove her socks and lick her feet; to her surprise, Hazuki agrees. Shiori becomes conscious about Hazuki obeying her orders, wondering how long their relationship would last.
