"Now I recall... the pleasure my body could experience." Aki Ayuna is an office worker who has been happily married for a decade, leading a serene life with her devoted husband... until she gets an invitation to a class reunion. That evening, Ayuna starts to reminisce about her former boyfriend and the close moments they had together, stirring up a longing she thought had disappeared. As she hesitates about attending the reunion, an old school friend sends her a message... a message that draws her back to the past she thought was left behind.
