I have been running this convenience store for ten years. A few years ago, due to the emergence of a large convenience store chain in the neighborhood, the store's revenue dropped significantly. Now I can no longer afford to hire part-time staff. I have to go to the store every day and almost can't go back home. When my relationship with my wife deteriorated, a housewife living in the neighborhood started working part-time here. She was also betrayed by her husband, so her situation was similar to mine. To alleviate each other's loneliness, we crossed the line. It was not about love or romance, just purely physical intimacy, filling the emptiness in our souls with physical pleasure. Whenever we had the opportunity, we sought each other out. Since the store was also empty, we almost made love all day. We promised to make love to forget all the worries. Some time later, my wife decided to leave with our child. Feeling disheartened, I closed the store. Aika then came to me, reminding me of our promise. I wanted to indulge in physical intimacy with Aika, forget everything, forget the current troubles...
