Motomu Shiragi is an ordinary university student whose quiet life takes an unexpected turn one summer day. When he lent a mere five hundred yen to a friend, he never imagined it would lead to such bizarre consequences. Without warning, his friend’s younger sister, Akari Miyamae, arrives at the door of his apartment with a startling declaration: until her brother repays the trivial debt, she intends to stay by his side as collateral, proudly calling herself his property. Left completely bewildered by this sudden arrangement, Motomu finds himself thrust into an unusual living situation with a girl who seems far too enthusiastic about the circumstances. As their unexpected cohabitation begins, questions linger in the air. What exactly is the secret behind this absurdly small loan, and what are Akari’s true intentions for showing up at his doorstep? Driven by a single coin and an inexplicable promise, the story unfolds into a delightfully sweet romantic comedy. Caught between confusion and the undeniable charm of his new housemate, Motomu must navigate the challenges of sharing his home while trying to uncover the mystery behind Akari’s sudden devotion.
