Yamada and Notani meet for the first time at an arcade game booth outside a candy store. Shy Yamada is 19, living alone and beset with unspoken tragedy. She doesn't work or study, and confesses to suffering from anxiety. Notani, an older, self-proclaimed ‘traveler', bursts with unrestrained extroversion.

Meanwhile, Notani's pessimistic views on dying and death.
