It's been a year since I lost my husband... Her daughter, Miku, is also married and lives alone. For her mother, Hitomi, only a few conversations with her son-in-law, Daichi, who occasionally comes to show her face, were the few pleasures. However, Hitomi, who has come to see Daichi as a man, cannot control the urge that smolders in her heart, and entrusts her to her. The relationship between the two who have crossed the line changes greatly, and the eyes are crazy about the warmth of the earth that she seeks every time she visits. But one day, Miku, who is suspicious of the two of them, visits her house.
