The existence that bothers me, who lives alone, is Mako, who lives in the opposite room. She spends her days with her husband almost every night, and I can see it from my room. I can't control my curiosity and ulterior motives, and I'm also me. One day, when I lost my desire and looked through the opposite window, I met Mako's eyes! ? Mako, who noticed her peeking at me, began the days when her husband brought me home to release her own desires during her business trip.
