Eri happily moves into a newly purchased second-hand house, but her joy casts a shadow over her relationship with her husband Osamu. Buried in overtime to pay off the mortgage, Osamu has grown distant, and their sex life has dwindled. Though lonely, Eri keeps her feelings to herself.

He invites Shuina to assess their home—a decision that will drastically alter their marriage.
