Mariko Suda owns a small second-hand book store in Tokyo and lives modestly. Today is her 42nd birthday. Every year, she bakes the number of cookies of her age and gives to people who celebrates her birthday believing that her dream will come true once she can give all the cookies away. As it were in the past, it seems that she can not give away all the cookies away this year as well. Then, wheelchaired Kyota Nemoto passes by and the BLUEs, a mysterious one who sells only things in blue, steals the cookies. Can Mariko and Kyota get cookies back and make Mariko's dream come true?
