Tsuki 50-man moratte mo Ikigai no nai Tonari no Onee-san ni 30-man de Yatowarete "Okaeri" tte Iu Oshigoto ga Tanoshii

Matsutomo is an exhausted salaryman trapped in a grueling corporate environment, enduring relentless exploitation under a supervisor who routinely dumps his own workload onto him. To make matters worse, none of his colleagues can seem to remember his actual name, casually addressing him as Matsumoto instead. Drained and unappreciated, he trudges through each day until one late night fundamentally shifts the trajectory of his life. Returning home after yet another punishing shift, Matsutomo encounters his neighbor, Saotome-san—a strikingly beautiful woman who has always kept him at a polite distance. Tonight, however, she finds herself in a desperate predicament: her phone, wallet, and apartment keys are locked inside her bag at a supplier's office three hours away. Worse still, crucial documents needed for an important meeting the following morning remain sealed within her inaccessible apartment. Ever the gentleman, Matsutomo steps in without hesitation, finding a way to resolve her crisis. Deeply moved by his selfless assistance, Saotome-san makes him an extraordinary offer—one so unexpected that he never even gets the chance to refuse it.
