A rent-collection service visits four adult tenants with overdue payments. Shiori, 20, is an art student whose unsuccessful exhibition left her deep in debt. Noa, 26, is a beauty consultant whose stress-driven spending, daytime drinking, figures, and adult toys drained her finances. Mikuru, 21, is an adult college student who lived luxuriously on her father's credit card until his business failed. Yuno, 22, is an office worker whose income vanished after someone fled overnight; because she treats her arrears casually, her belongings are seized to make the consequences clear.
