Synopsis

The heroine, Kazuha Oba, is a full-time housewife devoted to raising and educating her son.

Her marriage to Sosuke has grown strained due to their conflicting views on parenting. On top of that, Kazuha has never enjoyed sex because it has always been accompanied by pain, leaving their relationship far from intimate.

One day, the neighborhood association organizes an overnight hot spring trip for senior residents.

Masahiko, the chairman of the neighborhood association who lives next door, visits Kazuha during the day and asks her to accompany him on a preliminary inspection of the inn, explaining that he would like a woman's perspective since his wife is unavailable.

• Her body responds with excitement to raw desire, even as her mind resists.

• As her body is carefully and gently awakened, the pain she once associated with intimacy disappears.

• Having discovered pleasure for the first time, the once-reserved Kazuha gradually becomes captivated by desire.

Opening

Kazuha Oba is a devoted mother who places her son's education above everything else.

Because sex had always been painful, she regarded intimacy as nothing more than a means of having a child. After giving birth to her son, Yu, she steadfastly avoided any physical relationship with her husband, Sosuke.

One day, she is invited to join a preliminary inspection for a hot spring trip organized by the neighborhood association for its elderly members.

What she does not know is that Sosuke and the neighborhood chairman, Masahiko, have already made a secret agreement behind her back.

During the trip, Kazuha experiences intimacy without pain for the very first time... and slowly begins to transform into someone driven by newfound passion.
