My missing brother suddenly returned to his sister, who lives alone. However, his brother looks strange. All memories are ambiguous, even with blurring symptoms. He said "Congratulations" many times, remembering that her sister was pregnant, even though her symptoms didn't improve at all. One day, a man who said he was working in the same store as his brother came and it became clear how his brother lost his memory. A little hope can be seen beyond the natural appearance of people living in despair.
