Tập 15: Yumiko gặp khó khăn trong việc hoàn thành hạn chót của cuốn tiểu thuyết khi một sự cố lịch làm lặp lại ngày hôm trước.

15

On the tenth of the month, Yumiko has to finish her next novel before the deadline, but she needs more time to finish it. The next day, she is still not done, and does not rip the calendar date onto the following day, which inadvertently repeats the events of the previous day, though only Makoto and Yumiko have any knowledge of this.
