"Now I remember… How pleasurable my body could feel."

Aki Ayuna is an office worker who has been married for ten years, enjoying a quiet life with her loving husband... until she receives an invitation to a class reunion.

That night, Ayuna finds herself remembering her ex-boyfriend and the intimate experiences they once shared, awakening a desire she thought had long since faded.

As she wavers over whether to attend the reunion, she receives a message from an old school friend... A message calling her back to the past she believed was long buried.
