“I’d like to buy your time—for two hundred thousand yen a month.” For Sakata, the winter of his junior year brings nothing but loss. His mother is dead, his useless father is gone, and each day nearly costs him everything he has left. Then a young man named Nishikawa approaches him with an offer—and generous pay that could give his mother a proper funeral. However, the deal comes with several bizarre conditions that Sakata must meet: go to school every day, get into the same university as Nishikawa, and lastly, act like his friend until the end of their contract. As their bond deepens, the two boys starved for love must face the question neither dared to ask: Can a friendship built entirely on money turn into something real?
