Matsutomo is an exhausted employee of a shady company, burdened with multiple tasks given by an efficient delegating boss. His colleagues have mistakenly called him Matsumoto. Coincidentally, one evening on his way home from work, he encounters his stunning but distant neighbor, Saotome. He is shocked to discover that she has carelessly left her purse, phone, and apartment keys at a supplier's location three hours away, and crucial documents needed for a crucial meeting the next day are unreachable in her apartment. As a polite gentleman, Matsutomo aids her in solving the issue. In gratitude, Saotome extends to Matsutomo an irresistible opportunity.
