I live alone in an old apartment, and a cute woman with a lovely smile moves in next door to me. "Spring has come to me too!" I thought to myself, but then her handsome husband called out to me. "Are they a married couple...?" I thought, feeling empty as I slurped on some instant ramen, when I heard a voice leak out. It seems that the couple next door have been crazy about lovey-dovey sex ever since they moved in. From then on, it became my daily routine to secretly peek at the couple getting cozy with each other, day and night.
