Marriage is not like a lottery. Unlike a lottery, which has a clear winning prize, marriage holds an uncertain future. And so begins the story of Atsushi and Nanami in Shin-Koiwa. With their wedding set for tomorrow and both having taken time off work, the couple is busy preparing in the man's room. Filled with hope and excitement for their upcoming newlywed life in their new home next month, they reminisce about the past and talk enthusiastically about their honeymoon starting the day after tomorrow. Their hearts are overflowing with preparation for their new life together and anticipation for the future ahead.
