Yuu has just graduated and is now living alone, away from home. He is not used to the new lifestyle and is scolded by his boss every day. He is about to give up, but one day, a familiar woman is standing at the front door. It is his mother, Sachika. She has come because Yuu is worried about him. Eating his mother's home cooking for the first time in a while eases the Kokoro he has been going through every day. Sachika is staying over tonight, and as they sleep in the same futon, Yuu feels comfort and sexual desire as he smells his mother's familiar scent and feels her body heat.
