I have been running this convenience store for ten years. A few years ago, due to the emergence of large convenience store chains in the neighborhood, the store's revenue dropped sharply. Now I can no longer afford to hire part-time workers. I have to go to the store every day and can hardly return home. As my relationship with my wife deteriorated, a housewife living in the neighborhood started working part-time here. She herself was cheated on by her husband, so her situation is similar to mine. To alleviate our loneliness, we crossed boundaries. It wasn't a feeling of love or romance, just simply sex, filling the void in our souls with physical pleasure. Whenever there was an opportunity, we sought each other out. Since the store was also lacking customers, the two of us almost made love all day. We promised to have sex with each other to forget all our worries. After a while, my wife also decided to leave with our child. Very frustrated, I closed the store. Aika immediately came to me, reminding me of the promise we both made. I wanted to lose myself in sex with Aika, forgetting everything, forgetting all the current troubles...
