The ending for a young man who peeped on his neighbor's wife while masturbating

The existence that bothers me, who lives alone, is Mako, who lives in the opposite room. My husband and I do business almost every night, and I can see it from our room. I can't control my curiosity and ulterior motives, and I'm just me. One day, when I lost my desire and looked through the opposite window, I met Mako's eyes! ? Mako, who noticed me peeping, began the days when her husband took me home to relieve his desires while on a business trip.
