Shuu ni Ichido Classmate wo Kau Hanashi: Futari no Jikan, Iiwake no 5000-en

Once a week, Miyagi pays 5,000 yen to her classmate Sendai to buy three hours of Sendai’s time, which allows Miyagi to give her orders. Miyagi is at the bottom of the school caste while Sendai is at the top. The two, who have nothing to do with each other at school, spend time together after school under this contract. Miyagi’s orders are determined by her mood that day, and Sendai cannot disobey. One day after school… Miyagi calls Sendai to her room and gives her an unusual order.
