Yonemura is a convenience store supervisor who is in a relationship with Ando, a part-time employee who is over ten years his junior. Their relationship is not yet intimate, but since Ando is about to turn twenty, Yonemura is planning a special event for him. However, their time together is limited due to Yonemura's demanding schedule. The dynamic among them changes when Mitsuhara, a new part-timer, joins the store and often behaves inappropriately around Yonemura, causing tension between the three.
