Over the past 3 years, both of them had grown apart. “Venus” decided to quit his job. He planned to return to his hometown to take a career break until his passion for work was reignited. In the meantime, he killed boredom through helping with “Janus”, his older brother, who just opened a 24-hr. convenience store in a suburb. In the evenings, he would be responsible for small tasks such as delivering items to ‘regular customers’ whose residences were located on his way home. But one day, Venus met a customer who he had never met before. It surprisingly, turned out that such a customer was “Sky” who became a good-humored, highly energetic young doctor as always, despite mountains of workloads at the hospital. Upon seeing each other again, they couldn’t resist the feelings.
