A couple visits a guesthouse run by the wife's mother, Yuriko Hosaka. The wife married for love after meeting her husband at work, but after marriage, she stopped caring about him and settled into a lazy, unmotivated lifestyle. Although the husband suggested this countryside trip, his mother-in-law welcomed them with visible anticipation beneath her joy. Having managed the guesthouse single-handedly for years, Yuriko treats him with gentle warmth, slowly stirring emotions within him. Even at her parents' home, the wife's indifferent attitude remains unchanged, but the affectionate bond forming between husband and mother-in-law begins to shake his heart. In that moment when everything starts to shift, the husband's feelings can never return to how they once were.
