Despite being busy late into the night, Yu Chen and Hiromi Jounouchi didn't get much rest, but still needed to wake up early and be on time for work the next day.
This is also why the medical profession is prone to overwork. Although the official working hours are only eight hours a day, doctors often end up working overtime almost every day. There are always medical records to be organized or sudden emergency patients to attend to.
In a university hospital like the Eastern University Affiliated Hospital where Yu Chen and Hiromi Jounouchi worked, the need for overtime was actually not frequent, and when it was required, it usually just meant staying an extra one or two hours. Working late into the night, like they did yesterday, was in fact very rare.
