One morning, Kazue is nearly knocked over by a motorbike in front of an instrument store, breaking all the records that she was carrying. The two connect instantly and begin seeing each other every day. However, Iwai, Yukio’s foster parent, is concerned - Yukio had been exposed to the atomic bomb when he was four years old and had been showing symptoms of atomic radiation, hospitalizing him in the Genbaku Atomic Bomb Survivor’s Hospital. Unfortunately, nobody knows when the symptoms may return. When Yukio passes out from anemia during work, he decides to part with Kazue. A couple of days later, Yukio tells her of his destiny at the Hiroshima Peace Memorial Park, but Kazue passionately encourages him.
