Synopsis

This work is an infidelity suspense drama where the secret relationships of four men and women intricately intersect, and a married couple’s daily life transforms into psychological warfare after they cross the line. Miyamoto plays Matsumoto Naho, a housewife working part-time at a supermarket. In her second year of marriage to her husband Shogo, who works at a travel agency, she believed their marriage was harmonious, but becomes aware of their sexless relationship after a remark from a colleague. Feeling that things cannot continue this way, Naho resolves to make Shogo interested, but her efforts backfire.
 
Meanwhile, Shogo receives an affair proposition from his workplace colleague who asks him to become his “friend with benefits.” Naho, however, with her unfulfilled feelings, coincidentally reunites with her ex-boyfriend from high school, and begins seeking emotional support in his unchanged kindness.
