Kanna, a rookie bubble princess who works at a luxury soap shop. It was a job I started to fill my loneliness with my husband every day. One day, a young man, Sugiura, comes to Kanna. A naive young man who ejaculates only with foreplay because he is not used to women. However, due to his clumsy yet gentle personality, Sugiura begins to come into contact with Sugiura not as a soap lady but as a woman. The two put their lips together hoping that this time would never end. Their relationship gradually dwindles.
